lib msun remainder() function gives incorrect result on powerpc64, as reported
by rem_test.c.
Expected result is 4.9406564584124654e-324, but -4.9406564584124654e-324 is
given.
Reduced test case:
#include <openlibm.h>
#include <assert.h>
int main()
{
double x=-3.3770170061145426e-226;
double y=2.4703282292062327e-323;
double expected_rem = 4.9406564584124654e-324;
double rem;
rem = remainder(x, y);
assert(rem == expected_rem);
return(0);
}
* compile with "cc rem.c -lm"
