CLNG

CLNG(expression)

Returns the expression converted to a long data type (Long).

expression

The expression to evaluate and convert to a long.

REMARKS

* The Long data type is a Value data type.
* The "expression" can be any number between -2.1 E+9 and +2.1 E+9.
* If "expression" includes any fractions or decimals these are rounded.
* If "expression" is outside the range of the data type being converted to, an error occurs.
* Any fractional parts greater than 0.5 are rounded up.
* Any fractional parts less than 0.5 are rounded down.
* Any fractional parts equal to 0.5 are rounded to the nearest even number.
* This type of rounding is called banker's rounding and its purpose is to compensate for a bias that could accumulate when adding a lot of 0.5 fractions.
* You can use the CDBL function to return an expression converted to a Double data type.
* You can use the CINT function to return an expression converted to an Integer data type.
* You can use the CSNG function to return an expression converted to a Single data type.
* You can use the CLNGLNG function to return an expression converted to a LongLong (64 bit platform) data type.
* You can use the CLNGPTR function to return a LongPtr data type.
* For a full list of conversion functions refer to the Explicit Conversion page.
