For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings.
Since PHP 4.0.4, libbcmath is bundled with PHP. You don't need any external libraries for this extension.
These functions are only available if PHP was configured with --enable-bcmath. In PHP 3, these functions are only available if PHP was not configured with --disable-bcmath.
Windows versionen af PHP har indbygget support for denne udvidelse. Du behøver ikke indsætte ekstra udvidelser for at bruge disse funktioner.
Virkemåden af disse funktioner er berørt af indstillinger i php.ini.
