[neveranything]

I need a little help with my C++ programming. I don't know how to get a variable to round to the nearest cent.

I'm using double type variables for my decimals. Is there a way to format them for currency or do I need a different variable.

Hi,

I assume you're working in DOS...

This will print the number with 2 decimal places:

#include &ltstdlib.h>
#include &ltstdio.h>

int main()
{
  double number = 1.6759;

  // Using %.2f  to remove unwanted digits.
  printf("%f rounds to %.2f",number,number);
  return 0;
}

This will actually round the number off to 2 decimal
places, in case you need to do something with it:

#include &ltstdlib.h>
#include &ltstdio.h>

int main()
{
  double number = 1.6759;
  char *tmp;

  sprintf(tmp, "%.2f", number);
  number = atof(tmp);

  // Still using %.2f  to remove trailing zeroes.
  printf("Number is %.2f",number);
  return 0;
}
