numberp object [function]
-
-
T if object is number, namely integer or float.
Note that characters are also represented by numbers.
integerp object [function]
-
-
T if object is an integer number.
A float can be converted to an integer by
round, trunc and ceiling functions.
floatp object [function]
-
- T if object is a floating-point number.
An integer can be converted to a float by the float function.
zerop number [function]
