Each argument specifies + one character of the resulting string, with the first + argument specifying the first character, and so on, + from left to right. An argument is converted to a + character by applying the operation ToUint16_t and + regarding the resulting 16bit integeras the Unicode + encoding of a character. If no arguments are supplied, + the result is the empty string. + + This test covers Basic Latin (range U+0020 - U+007F) + + Author: christine@netscape.com + Date: 2 october 1997 +*/ + +var SECTION = "15.5.3.2-3"; +var VERSION = "ECMA_1"; +startTest(); +var TITLE = "String.fromCharCode()"; + +writeHeaderToLog( SECTION + " "+ TITLE); + +for ( CHARCODE = 0; CHARCODE < 256; CHARCODE++ ) { + new TestCase( SECTION, + "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", + ToUint16(CHARCODE), + (String.fromCharCode(CHARCODE)).charCodeAt(0) + ); +} +for ( CHARCODE = 256; CHARCODE < 65536; CHARCODE+=333 ) { + new TestCase( SECTION, + "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", + ToUint16(CHARCODE), + (String.fromCharCode(CHARCODE)).charCodeAt(0) + ); +} +for ( CHARCODE = 65535; CHARCODE < 65538; CHARCODE++ ) { + new TestCase( SECTION, + "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", + ToUint16(CHARCODE), + (String.fromCharCode(CHARCODE)).charCodeAt(0) + ); +} +for ( CHARCODE = Math.pow(2,32)-1; CHARCODE < Math.pow(2,32)+1; CHARCODE++ ) { + new TestCase( SECTION, + "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", + ToUint16(CHARCODE), + (String.fromCharCode(CHARCODE)).charCodeAt(0) + ); +} +for ( CHARCODE = 0; CHARCODE > -65536; CHARCODE-=3333 ) { + new TestCase( SECTION, + "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", + ToUint16(CHARCODE), + (String.fromCharCode(CHARCODE)).charCodeAt(0) + ); +} +new TestCase( SECTION, "(String.fromCharCode(65535)).charCodeAt(0)", 65535, (String.fromCharCode(65535)).charCodeAt(0) ); +new TestCase( SECTION, "(String.fromCharCode(65536)).charCodeAt(0)", 0, (String.fromCharCode(65536)).charCodeAt(0) ); +new TestCase( SECTION, "(String.fromCharCode(65537)).charCodeAt(0)", 1, (String.fromCharCode(65537)).charCodeAt(0) ); + +test(); + +function ToUint16( num ) { + num = Number( num ); + if ( isNaN( num ) || num == 0 || num == Number.POSITIVE_INFINITY || num == Number.NEGATIVE_INFINITY ) { + return 0; + } + + var sign = ( num < 0 ) ? -1 : 1; + + num = sign * Math.floor( Math.abs( num ) ); + num = num % Math.pow(2,16); + num = ( num > -65536 && num < 0) ? 65536 + num : num; + return num; +} + |
