  • SIGFPE

    From Fred J. Tydeman@21:1/5 to All on Wed Oct 23 05:10:30 2024
    Anyone know of any implementations that use SIGFPE?
    If so, how is it used?

    #include <limits.h>

    int main(void)
    {
    int a = INT_MIN, b = -1;
    return a / b;
    }

    Oops. I see I asked the wrong question.

    Anyone know of any implementations where the standard library functions use SIGFPE?
    If so, how is it used?

    I see I asked the wrong question.
    Anyone know of any standard C libaray implementations that use SIGFPE?
    If so, how is it used?

    ...

    "... the functions in <math.h> ... Each function shall execute as if it
    were a single operation without raising SIGFPE ..." (7.12.1p1).
