CByte Function
Returns an expression that has been converted to a Variant of subtype
Byte.
CByte(expression)
The expression argument is any valid expression.
Remarks
In general, you can document your code using the subtype 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.
Use the CByte function to provide internationally aware conversions
from any other data type to a Byte subtype. 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 subtype,
an error occurs. The following example uses the CByte function to convert
an expression to a byte: Dim MyDouble, MyByte
MyDouble = 125.5678 ' MyDouble is a Double.
MyByte = CByte(MyDouble) ' MyByte contains 126.
