|n||The number to 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...
val = floor( 3.9 );
This will set val to 3.
