int main()
{
PRINT(1.0 / 0.0);
PRINT(-1.0 / 0.0);
PRINT(atanf(1.0 / 0.0));
PRINT(atanf(-1.0 / 0.0));
return 0;
}
prints
1.0 / 0.0 = inf
-1.0 / 0.0 = -inf
atanf(1.0 / 0.0) = 1.570796
atanf(-1.0 / 0.0) = -1.570796
The changed function was problematic for values like ...commit 7a2bd361a668eae093e43f4d18cff12f3172f56d (HEAD -> master, origin/master, origin/HEAD)
