Converts numeric or string expression to 64-bit unsigned integer (Ulongint)

Syntax

declare function Culngint ( byval expression as datatype ) as ulongint

Type typename

declare operator cast ( ) as ulongint

End Type

Usage

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

Parameters

expression

a numeric, string, or pointer expression to cast to a Ulongint value

datatype

any numeric, string, or pointer data type

typename

a user defined type

Return Value

A Ulongint value.

Description

The Culngint function rounds off the decimal part and returns a 64-bit Ulongint value. The function does not check for an overflow, and results are undefined for values which are less than 0 or larger than 18 446 744 073 709 551 615. Additionally, casts from floating-point expressions are currently not guaranteed to work for values higher than 2^63 (9 223 372 036 854 775 808).

The name can be explained as 'Convert to Unsigned LoNG INTeger'.

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

Examples

start GeSHi

' Using the CLNGINT function to convert a numeric value

'Create an UNSIGNED LONG INTEGER variable
Dim numeric_value As ULongInt

'Convert a numeric value
numeric_value = CULngInt(12345678.123)

'Print the result, should return 12345678
Print numeric_value
Sleep

end GeSHi
