floor

Returns the floor of n, that is, n rounded down to an integer. This is similar to the round() function, but it only rounds down, no matter what the decimal value, so floor(5.99999) will return 5, as will floor(5.2), floor(5.6457) etc...

Syntax:

floor(n);

Returns:

Real

Example:

val = floor( 3.9 );

This will set val to 3.
