Comment(by dimpase):
The last comment makes no real sense. In fact, the bug(s) are already in
the
Compare the outputs of the following on ARM and on x86:
{{{
#include <stdio.h>
#include <math.h>
static long double xxx=4.78749174278204599545L;
int main ()
{
printf("xxx=%.20Lf\n", xxx);
printf("exp(xxx)=%.20Lf\n", expl(xxx));
return 0;
}
}}}
On ARM:
{{{
xxx=4.78749174278204581157
exp(xxx)=119.99999999999997157829
}}}
On x86_64:
{{{
xxx=4.78749174278204599545
exp(xxx)=120.00000000000000014572
}}}
