#include <stdio.h>

void main()
{
 int hours,ovehrs,amount;
     
     printf(" Please enter the amount of standard hours you worked ");
          scanf("%d", &hours);
     
     printf("\n Now how many Hours overtime you worked ");
          scanf("%d", &ovehrs);
{
 float pounds,amount;
 
      printf(" Enter Hourly rate ");
           scanf("%f", &pounds);
      amount = (float)hours*(float)pounds;

notice .2f instead of f ... that's how you specify precision

from UNIX man pages for fprintf ( printf is essentially fprintf to stdout )
-=-=-=-=-=-==--=-=-=-=-=-=-
An optional precision that gives the minimum number of digits to appear for the d, i, o, u, x and X conversions; the number of digits to appear after the radix character for the e, E and f conversions; the maximum number of significant digits for the g and G conversions; or the maximum number of bytes to be printed from a string in s  and S  conversions. The precision takes the form of a period (.) followed either by an asterisk (*), described below, or an optional decimal digit string, where a null digit string is treated as 0. If a precision appears with any other conversion character, the behaviour is undefined.
