c - What is the difference between lroundf(), floor() and nearbyintf()? -

-

I know that the above mentioned float value is used to round and double value. But can someone please explain how to eliminate the values ​​of each one? I could not find any documents for this.

View the manual page ("Know Google for Google" whenever there is a Library function ") :

  • - Round to the nearest integer, away from zero
  • - Not a bigger integral value greater than logic
  • - Integral value in floating-point format
