CUInt
Converts numeric or string expression to a `UInteger` or `UInteger<bits>`
Syntax
`
Declare Function CUInt ( ByVal expression As datatype ) As UInteger
Declare Function CUInt<bits> ( ByVal expression As datatype ) As UInteger<bits>
Type typename
Declare Operator Cast ( ) As UInteger
Declare Operator Cast ( ) As UInteger<bits>
End Type
`
Usage
`
result = CUInt( numeric expression )
result = CUInt( string expression )
result = CUInt( user defined type )
`
Parameters
`bits`
A numeric constant expression indicating the size in bits of unsigned integer desired. The values allowed are `8`, `16`, `32` or `64`.
`expression`
a numeric, string, or pointer expression to cast to a `UInteger` or `Uintger<bits>` value
`datatype`
any numeric, string, or pointer data type
`typename`
a user defined type
Return Value
A `UInteger` or `UInteger<bits>` containing the converted value.
Description
The `CUInt` function rounds off the decimal part and returns a `UInteger` value, or if a `bits` value is supplied, an unsigned integer type of the given size.
The function does not check for an overflow; for example, for a 32-bit `UInteger` results are undefined for values which are less than `0` or larger than `4` `294` `967` `296`.
The name can be explained as 'Convert to Unsigned INTeger'.
If the argument is a string expression, it is converted to numeric by using `ValUInt` or `ValULng`, depending on the size of the result type.
Example
`
' Using the CUINT function to convert a numeric value
'Create an UNSIGNED INTEGER variable
Dim numeric_value As UInteger
'Convert a numeric value
numeric_value = CUInt(300.23)
'Print the result = 300
Print numeric_value
