Question

the data-type ‘float’ displays decimal numbers. by default my compiler displays up-to 6 decimals. i want to see only two decimals. for eg , when the compiler performs the operation “c=2/3”
it displays “0.666666667”. i want to see only “0.67” in my output screen.
so what necessary changes should i make in the C program?

Answer 1

You can use a format specifier to limit it to 2 decimal places when outputting the number using printf.

int main() {
  double d = 2.0 / 3.0;
  printf("%.2f\n",d);
  return 0;
}

Here’s the output:

> "c:\windows\system32\cmd.exe" /c c:\temp\temp.exe
0.67

> Terminated with exit code 0.
