Argument

1. argument-1 must be of class "numeric" and the value v of argument-1 must lie in the range -10³¹ < v < 10³¹

Returned values

1. If the value of argument-1 is zero, the returned value is zero.

2. If the value of argument-1 is positive, the returned value is the greatest integer less than or equal to the value of argument-1. For example, if the value of argument-1 is +1.5, +1 is returned.
