float remainder with infinity/zero operand(s) is not NaN on win32.

Name: akC45999 Date: 01/13/97



The Java Virtual Machine, section drem, claims:

If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.

Meanwhile, following test fails:

--------------------- drem00101.java


package javasoft.sqe.tests.vm.frem.frem003.frem00301;


import java.io.PrintStream;
import java.lang.Float;


public class frem00301
{
public static void main(String argv[])
{
System.exit(run(argv, System.out));
}

public static int run(String argv[], PrintStream out)
{
float negInf = Float.NEGATIVE_INFINITY;
float posInf = Float.POSITIVE_INFINITY;
float negZero = -0.0f;
float posZero = +0.0f;
float negVal = -3.14f;

if (! Float.isNaN(negInf % 3.14f))
return 2;
else if (! Float.isNaN(negInf % negVal))
return 2;
else if (! Float.isNaN(negInf % negInf))
return 2;

return 2;
else if (! Float.isNaN(negInf % negZero))
