String Question in C

Amaru · 2005-05-30 18:18:40

In C, if i have a char array char string1[] = "532432" how do i 1) convert that string to a double or float 2) convert that double or float back to a string? atof doesn't seem to work for me in the way its described online.

What does:
double foo; foo = atof(string1); printf("foo=\"%8.2f\"", foo);
give you?

In what way is atof() not working compared to man pages?

Forgot to mention sprintf()/snprintf() for reversal.

By the way, in general, it's better to avoid using floats; most (all?) library functions use doubles.
