The BcMath\Number class

(PHP 8 >= 8.4.0)

Einführung

A class for an arbitrary precision number. These objects support overloaded arithmetic and comparison operators.

Hinweis: This class is not affected by the bcmath.scale INI directive set in php.ini.

Hinweis: The behavior of an overloaded operator is the same as specifying null for the scale parameter on the corresponding method.

}

value: A string representation of an arbitrary precision number.
scale: The scale value currently set on the object. For objects resulting from calculations, this value is automatically computed and set, unless the scale parameter was set in the calculation method.
