Description

Converts expression to a Byte data type. If the expression to be converted is a string, the string must be capable of conversion to a numeric expression; this can be checked using the IsNumeric function. If expression evaluates to less than 0 or more than 255, an exception is generated. If the value of expression is not a whole number, CByte rounds the number prior to conversion.
