CLngInt
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`.
Example
`
' 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
