CUByte
 
Converts numeric or string expression to an unsigned byte (UByte)

Syntax

Declare Function CUByte ( ByVal expression As datatype ) As UByte

Type typename
End Type

Usage

result = CUByte( numeric expression )
result = CUByte( string expression )
result = CUByte( user defined type )

Parameters

expression
a numeric, string, or pointer expression to cast to a UByte value
datatype
any numeric, string, or pointer data type
typename
a user defined type

Return Value

A UByte value.

Description

The CUByte function rounds off the decimal part and returns a 8-bit UByte value. The function does not check for an overflow, and results are undefined for values which are less than 0 or larger than 255.

The name can be explained as 'Convert to Unsigned Byte'.

If the argument is a string expression, it is converted to numeric by using ValUInt.

Example

' Using the CUBYTE function to convert a numeric value

'Create an UNSIGNED BYTE variable
Dim numeric_value As UByte

'Convert a numeric value
numeric_value = CUByte(123.55)

'Print the result, should return 124
Print numeric_value
Sleep
