Typecasting Functions
Typecasting allows you to convert between data subtypes.
§ CInt(expression) casts expression to an integer. If expression is a
floating-point value or a currency value, it is rounded. If it is a string that
looks like a number, it is turned into that number and then rounded if
necessary. If it is a Boolean value of True, it becomes -1. False becomes 0.
It also must be within the range that an integer can store.
§ CByte(expression) casts expression to a byte value provided that
expression falls between 0 and 255. expression should be numeric or
something that can be cast to a number.
§ CDbl(expression) casts expression to a double, expression should be
numeric or something that can be cast to a number.
§ CSng(expression) casts expression to a single. It works like CDbl(), but
must fall within the range represented by a single.
§ CBool(expression) casts expression to a Boolean value. If expression is
zero, the result is False. Otherwise, the result is True. Expression should be
numeric or something that can be cast to a number.

should be numeric or something that can be cast to a number.
