Converts an expression to a Byte.
CByte(expression)
The expression argument is any valid numeric or string expression.
In general, you can document your code using the data type conversion functions to show that the result of some operation should be expressed as a particular data type rather than the default data type. For example, use CByte to force byte arithmetic in cases where currency, single-precision, double-precision, or integer arithmetic normally would occur.
You should use the CByte function instead of Val to provide internationally-aware conversions from any other data type to a Byte. For example, different decimal separators are properly recognized depending on the locale setting of your system, as are different thousand separators.
If expression lies outside the acceptable range for the Byte data type, an error occurs.
Data Type Summary.
This example uses the CByte function to convert an expression to a Byte.
MyDouble = 125.5678 ' MyDouble is a Double.= CByte(MyDouble) ' MyByte contains 126.
