In C and C++, the remainder operator accepts only integral - operands, but in ECMAScript, it also accepts floating-point operands. - - The result of a floating-point remainder operation as computed by the % - operator is not the same as the "remainder" operation defined by IEEE 754. - The IEEE 754 "remainder" operation computes the remainder from a rounding - division, not a truncating division, and so its behavior is not analogous - to that of the usual integer remainder operator. Instead the ECMAScript - language defines % on floating-point operations to behave in a manner - analogous to that of the Java integer remainder operator; this may be - compared with the C library function fmod. - - The result of a ECMAScript floating-point remainder operation is determined by the rules of IEEE arithmetic: - - If either operand is NaN, the result is NaN. - The sign of the result equals the sign of the dividend. - If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN. - If the dividend is finite and the divisor is an infinity, the result equals the dividend. - If the dividend is a zero and the divisor is finite, the result is the same as the dividend. - In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r - from a dividend n and a divisor d is defined by the mathematical relation r = n (d * q) where q is an integer that - is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as - possible without exceeding the magnitude of the true mathematical quotient of n and d. - - Author: christine@netscape.com - Date: 12 november 1997 -*/ - var SECTION = "11.5.3"; - var VERSION = "ECMA_1"; - startTest(); - var testcases = getTestCases(); - var BUGNUMBER="111202"; - - writeHeaderToLog( SECTION + " Applying the % operator"); - test(); - -function test() { - for ( tc=0; tc < testcases.length; tc++ ) { - testcases[tc].passed = writeTestCaseResult( - testcases[tc].expect, - testcases[tc].actual, - testcases[tc].description +" = "+ - testcases[tc].actual ); - - testcases[tc].reason += ( testcases[tc].passed ) ?
