RE: [gtk-list] string to double (or float) conversion

[Tony Gale <gale syntax dera gov uk>]

Make sure you include an appropriate header file to get the strtod
definition, otherwise it will assume int. Try:

#include <stdio.h>
#include <stdlib.h>

void main()
{

char *ch;
float f;
ch = "2345.235";
f = strtod (ch,NULL);
printf("%f\n", f);
}
