How do I restrict a float value to only two places after the decimal point in C?

Question

How can I round a float value (such as 37.777779) to two decimal places (37.78) in C?

Answer 1

printf("%.2f", 37.777779);

If you want to write to C-string:

char number[24]; // dummy size, you should take care of the size!
sprintf(number, "%.2f", 37.777779);
