CBool Function

Synopsis

CBool(expression)

expression required; String or Numeric

Any numeric expression or a string representation of a numeric value

Named Arguments

No

Return Value

expression converted to Boolean data type (True or False)

Description

Casts expression as a Boolean data type. When a numeric value is converted to Boolean, any nonzero value is converted to True, and zero is converted to False.

If the expression to be converted is a string, the string must be capable of being evaluated as a number, or it must be "True" or "False". Any other string generates an exception. For example, CBool("one") results in a type mismatch error, whereas CBool("1") is converted to True, and CBool("True") is converted to True.
