CUByte
Converts numeric or string expression to an unsigned byte (UByte)
result = CUByte( numeric expression )
result = CUByte( string expression )
result = CUByte( user defined type )
expression
The CUByte function rounds off the decimal part and returns a 8 bit UByte value. The function does not check for an overflow, so be sure not to pass a value thats less/larger then 0 to 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.
Syntax
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
datatypeany numeric, string, or pointer data type
typenamea user defined type
Return 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, so be sure not to pass a value thats less/larger then 0 to 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
'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
