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

Syntax

declare function Clngint ( byval expression as datatype ) as longint

Type typename

declare operator cast ( ) as longint

End Type

Usage

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

Parameters

expression

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

datatype

any numeric, string, or pointer data type

typename

a user defined type

Return Value

A Longint value.

Description

The Clngint function rounds off the decimal part and returns a 64-bit Longint value. The function does not check for an overflow, and results are undefined for values which are less than -9 223 372 036 854 775 808 or larger than 223 372 036 854 775 807.

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

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

Examples

start GeSHi

' Using the CLNGINT function to convert a numeric value

'Create an LONG INTEGER variable
Dim numeric_value As LongInt

'Convert a numeric value
numeric_value = CLngInt(-12345678.123)

'Print the result, should return -12345678
Print numeric_value
Sleep

end GeSHi
