Gay, downloaded from - * http://www.netlib.org/fp/dtoa.c on April 15, 2009 and modified for - * inclusion into the Python core by Mark E. T. Dickinson and Eric V. Smith. - * It was taken from Python distribution then and imported into sphinxbase. - * Python version is preferred due to cleanups, though original - * version at netlib is still maintained. - * - * Please remember to check http://www.netlib.org/fp regularly for bugfixes and updates. - * - * The major modifications from Gay's original code are as follows: - * - * 0. The original code has been specialized to Sphinxbase's needs by removing - * many of the #ifdef'd sections. In particular, code to support VAX and - * IBM floating-point formats, hex NaNs, hex floats, locale-aware - * treatment of the decimal point, and setting of the inexact flag have - * been removed. - * - * 1. We use cdk_calloc and ckd_free in place of malloc and free. - * - * 2. The public functions strtod, dtoa and freedtoa all now have - * a sb_ prefix. - * - * 3. Instead of assuming that malloc always succeeds, we thread - * malloc failures through the code. The functions - * - * Balloc, multadd, s2b, i2b, mult, pow5mult, lshift, diff, d2b - * - * of return type *Bigint all return NULL to indicate a malloc failure. - * Similarly, rv_alloc and nrv_alloc (return type char *) return NULL on - * failure. bigcomp now has return type int (it used to be void) and - * returns -1 on failure and 0 otherwise. sb_dtoa returns NULL - * on failure. sb_strtod indicates failure due to malloc failure - * by returning -1.0, setting errno=ENOMEM and *se to s00. - * - * 4. The static variable dtoa_result has been removed. Callers of - * sb_dtoa are expected to call sb_freedtoa to free the memory allocated - * by sb_dtoa. - * - * 5. The code has been reformatted to better fit with C style. - * - * 6. A bug in the memory allocation has been fixed: to avoid FREEing memory - * that hasn't been MALLOC'ed, private_mem should only be used when k <= - * Kmax. - * - * 7. sb_strtod has been modified so that it doesn't accept strings with - * leading whitespace. - * - ***************************************************************/ - -/* Please send bug reports for the original dtoa.c code to David M.

With IEEE arithmetic, ties are - * broken by the IEEE round-even rule. Otherwise ties are broken by - * biased rounding (add half and chop). - * - * Inspired loosely by William D. Clinger's paper "How to Read Floating - * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101]. - * - * Modifications: - * - * 1. We only require IEEE, IBM, or VAX double-precision - * arithmetic (not IEEE double-extended). - * 2. We get by with floating-point arithmetic in a case that - * Clinger missed -- when we're computing d * 10^n - * for a small integer d and the integer n is not too - * much larger than 22 (the maximum integer k for which - * we can represent 10^k exactly), we may be able to - * compute (d*10^k) * 10^(e-k) with just one roundoff. - * 3. Rather than a bit-at-a-time adjustment of the binary - * result in the hard case, we use floating-point - * arithmetic to determine the adjustment to within - * one bit; only in really hard cases do we need to - * compute a second residual. - * 4. Because of 3., we don't need a large table of powers of 10 - * for ten-to-e (just some small tables, e.g. of 10^k - * for 0 <= k <= 22). - */ - -/* Linking of sphinxbase's #defines to Gay's #defines starts here. */ - -#ifdef HAVE_CONFIG_H -#include "config.h" -#endif - -#include <errno.h> -#include <string.h> -#include <assert.h> -#include <stdio.h> - -#include <sphinxbase/ckd_alloc.h> -#include <sphinxbase/prim_type.h> - -#ifdef WORDS_BIGENDIAN -#define IEEE_MC68k -#else -#define IEEE_8087 -#endif - -#define Long int32 /* ZOMG */ -#define ULong uint32 /* WTF */ -#ifdef HAVE_LONG_LONG -#define ULLong uint64 -#endif - -#define MALLOC ckd_malloc -#define FREE ckd_free - -#define DBL_DIG 15 -#define DBL_MAX_10_EXP 308 -#define DBL_MAX_EXP 1024 -#define FLT_RADIX 2 - -/* maximum permitted exponent value for strtod; exponents larger than - MAX_ABS_EXP in absolute value get truncated to +-MAX_ABS_EXP.

See ISPEC for a description of - the parameters. - - This version provides a set of parameters which should give good, - but not optimal, performance on many of the currently available - computers. Users are encouraged to modify this subroutine to set - the tuning parameters for their particular machine using the option - and problem size information in the arguments. - - This routine will not function correctly if it is converted to all - lower case. Converting it to all upper case is allowed. - - Arguments - ========= - - ISPEC (input) INTEGER - Specifies the parameter to be returned as the value of - ILAENV. - = 1: the optimal blocksize; if this value is 1, an unblocked - algorithm will give the best performance. - = 2: the minimum block size for which the block routine - should be used; if the usable block size is less than - this value, an unblocked routine should be used. - = 3: the crossover point (in a block routine, for N less - than this value, an unblocked routine should be used) - = 4: the number of shifts, used in the nonsymmetric - eigenvalue routines - = 5: the minimum column dimension for blocking to be used; - rectangular blocks must have dimension at least k by m, - where k is given by ILAENV(2,...) and m by ILAENV(5,...) - = 6: the crossover point for the SVD (when reducing an m by n - matrix to bidiagonal form, if max(m,n)/min(m,n) exceeds - this value, a QR factorization is used first to reduce - the matrix to a triangular form.) - = 7: the number of processors - = 8: the crossover point for the multishift QR and QZ methods - for nonsymmetric eigenvalue problems. - = 9: maximum size of the subproblems at the bottom of the - computation tree in the divide-and-conquer algorithm - (used by xGELSD and xGESDD) - =10: ieee NaN arithmetic can be trusted not to trap - =11: infinity arithmetic can be trusted not to trap - - NAME (input) CHARACTER*(*) - The name of the calling subroutine, in either upper case or - lower case. - - OPTS (input) CHARACTER*(*) - The character options to the subroutine NAME, concatenated - into a single character string. For example, UPLO = 'U', - TRANS = 'T', and DIAG = 'N' for a triangular routine would - be specified as OPTS = 'UTN'. - - N1 (input) INTEGER - N2 (input) INTEGER - N3 (input) INTEGER - N4 (input) INTEGER - Problem dimensions for the subroutine NAME; these may not all - be required. - - (ILAENV) (output) INTEGER - >= 0: the value of the parameter specified by ISPEC - < 0: if ILAENV = -k, the k-th argument had an illegal value. - - Further Details - =============== - - The following conventions have been used when calling ILAENV from the - LAPACK routines: - 1) OPTS is a concatenation of all of the character options to - subroutine NAME, in the same order that they appear in the - argument list for NAME, even if they are not used in determining - the value of the parameter specified by ISPEC. - 2) The problem dimensions N1, N2, N3, N4 are specified in the order - that they appear in the argument list for NAME. N1 is used - first, N2 second, and so on, and unused problem dimensions are - passed a value of -1. - 3) The parameter value returned by ILAENV is checked for validity in - the calling subroutine.
