CULngIntfunction

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

Converting Data Typesfunctiondocumented

Syntax

Declare Function CULngInt ( ByVal expression As datatype ) As ULongInt
Type typename
Declare Operator Cast ( ) As ULongInt
End Type

Parameters

NameDescription
expressiona numeric, string, or pointer expression to cast to a ULongInt value
datatypeany numeric, string, or pointer data type
typenamea 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.

Remarks

Usage


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