<para>

|
Returns a string containing <parameter>number</parameter>
|
|
represented in base <parameter>tobase</parameter>. The base in
|
|
which <parameter>number</parameter> is given is specified in
|
|
<parameter>frombase</parameter>. Both
|
|
<parameter>frombase</parameter> and <parameter>tobase</parameter>
|
|
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.

<function>base_convert</function> may lose precision on large numbers
|
|
due to properties related to the internal "double" or "float" type used.

section in the manual for more specific information and limitations.
