	A ##[[KeyPgBoolean Boolean]]## value.

{{fbdoc item="desc"}}
	The ##**Cbool**## function converts a zero value to ##[[KeyPgFalse False]]## and a non-zero value to ##[[KeyPgTrue True]]##.

	The name can be explained as 'Convert to Boolean'.

	If the argument is a string expression, it is converted to boolean using a case insensitive to the string "false" to return a ##[[KeyPgFalse False]]## value or "true" to return a ##[[KeyPgTrue True]]## value.
