gmp_sqrtremSquare root with remainder

### Description

array gmp_sqrtrem ( resource \$a )

Calculate the square root of a number, with remainder.

### Parameters

a

The number being square rooted.

It can be either a GMP number resource, or a numeric string given that it is possible to convert the latter to a number.

### Return Values

Returns array where first element is the integer square root of a and the second is the remainder (i.e., the difference between a and the first element squared).

### Examples

Example #1 gmp_sqrtrem() example

```<?phplist(\$sqrt1, \$sqrt1rem) = gmp_sqrtrem("9"); list(\$sqrt2, \$sqrt2rem) = gmp_sqrtrem("7"); list(\$sqrt3, \$sqrt3rem) = gmp_sqrtrem("1048576"); echo gmp_strval(\$sqrt1) . ", " . gmp_strval(\$sqrt1rem) . "\n"; echo gmp_strval(\$sqrt2) . ", " . gmp_strval(\$sqrt2rem) . "\n"; echo gmp_strval(\$sqrt3) . ", " . gmp_strval(\$sqrt3rem) . "\n";?>```

The above example will output:

```3, 0
2, 3
1024, 0
```
