It appeared that one specific case fails. I am running cygwin-1.5.25-15. Test cases: #include int main() { char *foo1 = "10i"; char *foo2 = "0i"; char *foo3 = "0.0i"; char *foo4 = "1.0i"; char *foo5 = "0.1i"; float f; printf("%d ", sscanf(foo1, "%f", &f)); printf("%f\n", f); printf("%d ", sscanf(foo2, "%f", &f)); printf("%f\n", f); printf("%d ", sscanf(foo3, "%f", &f)); printf("%f\n", f); printf("%d ", sscanf(foo4, "%f", &f)); printf("%f\n", f); printf("%d ", sscanf(foo5, "%f", &f)); printf("%f\n", f); } As the scanf man page specifies, 'i' is not supposed to be converted, only the number part is supposed to be recognized. On Cygwin: $ ./test 1 10.000000 0 10.000000 1 0.000000 1 1.000000 1 0.100000 On Linux (Ubuntu 8.04) and MinGW, the second case succeeds, the result being the same as the third case. I've done some googling, and haven't found anything related to this behaviour. -- Cheers, Kein-Hong Man (esq.)
