CByte - function of language VBScript

The conversion functions can be used e.g. if you want some operation result to be expressed as a particular data type (rather than the default data type). For example, use CByte to force Byte data type in cases where single-precision, double-precision, or integer arithmetic normally would occur.

Use the CByte function to provide internationally aware conversions from any other data type to a Byte type. For example, different decimal separators are properly recognized depending on the locale setting of Windows system, as are different thousand separators.

If expression lies outside the acceptable range for the Byte type, then an error occurs.
