VARIANT_DIV(3) 1 VARIANT_DIV(3)
variant_div - Returns the result from dividing two variants
SYNOPSIS
mixed variant_div (mixed $left, mixed $right)
DESCRIPTION
Divides $left by $right and returns the result.
PARAMETERS
o $left
- The left operand.
o $right
- The right operand.
Note
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(3) in PHP cor-
responds to VarAdd() in the MSDN documentation.
