Math.Floor Function

Rounds variables toward negative infinity.

Pascal

function Floor(const X: Extended): Integer;

C++

int Floor(const Extended X);

Call Floor to obtain the highest integer less than or equal to X. For example:

Floor(-2.8) = -3

Floor(2.8) = 2

Floor(-1.0) = -1

Note: The absolute value of X must be less than MaxInt.
