Purpose:
takes a decimal or double number and returns a value
that represents the next equal or higher whole number.
Although the result is a whole number, it is returned as a
the same data type that was passed in. Math.Floor is different
in that it rounds down to the next whole number that is equal
or less than the number that is given.

Syntax:
Ceiling(decimalnumber)

Parameters Description
decimalnumber decimal number

Result Data Type Description

Syntax2:
Ceiling(doublenumber)

Parameters Description
doublenumber double precision floating point number

Result Data Type Description
double precision floating point number closest whole number equal or higher
