# variant_idiv

(PHP 5)

variant_idiv -- Converts variants to integers and then returns the result from dividing them

## Description

mixed variant_idiv ( mixed left, mixed right)

Converts left and right to integer values, and then performs integer division according the following rules:

Tabela 1. Variant Integer Division Rules

If | Then
--- | ---
Both expressions are of the string, date, character, boolean type | Division and integer is returned
One expression is a string type and the other a character | Division
One expression is numeric and the other is a string | Division
Both expressions are numeric | Division
Either expression is NULL | NULL is returned
Both expressions are empty | A com_exception with code `DISP_E_DIVBYZERO` is thrown

See also variant_div().

> Nota: As with all the variant arithmetic functions, the parameters for this function can be either a PHP native type (integer, string, floating point, boolean or `NULL`), or an instance of a COM, VARIANT or DOTNET class. PHP native types will be converted to variants using the same rules as found in the constructor for the VARIANT class. COM and DOTNET objects will have the value of their default property taken and used as the variant value.

> The variant arithmetic functions are wrappers around the similarly named functions in the COM library; for more information on these functions, consult the MSDN library. The PHP functions are named slightly differently; for example variant_add() in PHP corresponds to VarAdd() in the MSDN documentation.
