# Net_IPv4::ip2double()

Net_IPv4::ip2double() -- Converts an IP address to a PHP double.

## Synopsis

    require_once 'Net/IPv4.php';

``float ip2double` (string $ip_addr)`

## Description

Converts an IP address to a PHP double - for example "192.168.1.0" to "3232235776". A double is, in contrast to ip2long's integer, not signed and may be more comfortable when presented to the user. It can still be reconverted with PHP's long2ip().

## Note

This function can be called statically.
