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

Syntax

Type typename

End Type

Parameters

Name		Description
`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.
