see help example for "atoi"

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

int main(void)
{
int n;
char *str = &quot;12345.67&quot;;

n = atoi(str);
printf(&quot;string = %s integer = %d\n&quot;, str, n);
return 0;
}

on the example above the output will be 12345 because atoi will stop at the decimal. If you want to get the full decimal value, use atof.

I didnt see the decimal when I copied and
pasted. My fingers are quicker than
my brain.
