# base_convert

(PHP 4, PHP 5)

base_convert — Convert a number between arbitrary bases

### Описание

string base_convert ( string `$number` , int `$frombase` , int `$tobase` )

Returns a string containing `number` represented in base `tobase` . The base in which `number` is given is specified in `frombase` . Both `frombase` and `tobase` have to be between 2 and 36, inclusive. Digits in numbers with a base higher than 10 will be represented with the letters a-z, with a meaning 10, b meaning 11 and z meaning 35.

Внимание

base_convert() may lose precision on large numbers due to properties related to the internal "double" or "float" type used. Please see the Floating point numbers section in the manual for more specific information and limitations.
