Hello,
I discovered that TCC and GCC gave different results in a long algorithm.
I focused on the bug, and I could reduce the code to the following lines. If I
reduce further the code, the bug disappears.
I think the code does not require further comments... I'm using tcc version
0.9.27 (x86_64 Windows)
The same calculation gives me 2 different values : 0.993013 0.860892 wheras it
should give 0.993013 only (tells GCC).
#include <stdio.h>
#include <math.h>
int main(){
double s = .7;
double a = (1. - .1 * s) / (1. + .1 * s);
double b = pow(a, .05);
double c = pow( ((1. - .1 * s) / (1. + .1 * s)), .05);
printf("%f %f \n", b, c);
}
==> can anyone reproduce this?
==> any clue about the cause?
Thanks a lot !
