How to create floats from const char* in C?

Question

Trivial question, please help.

I need to convert a string literal like "111.25" to floating point number.
atof() fails me as it returns 1111 and discards .25?

You must have forgotten to include the header file "stdlib.h" or maybe you used ""atoi"" by mistake instead of ""atof""

The below code works fine for me --

#include<stdio.h>
#include<stdlib.h>
main()
{
char *str="111.25";
float x;

x=atof(str);
printf("x=%f\n",x);
}

Output :

x=111.250000
