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

You can still use:

float ceilf(float x); // don't forget #include  and link with -lm.

example:

float valueToRound = 37.777779;
float roundedValue = ceilf(valueToRound * 100) / 100;
