# Deprecation: #103785 - Deprecate MathUtility::convertToPositiveInteger()

See [forge#103785](https://forge.typo3.org/issues/103785)

## Description

TYPO3 has the method `MathUtility::convertToPositiveInteger()` to ensure
that an integer is always positive. However, the method is rather
"heavy" as it calls `MathUtility::forceIntegerInRange()` internally and
therefore misuses a clamp mechanism to convert the integer to a positive number.

Also, the method name doesn't reflect what the method actually does. Negative
numbers are not converted to their positive counterpart, but are swapped with
`0`. Due to the naming issue and the fact that the method can be replaced by a
simple `max()` call, the method is therefore deprecated.

## Impact

Calling `MathUtility::convertToPositiveInteger()` will trigger a PHP
deprecation warning.

## Affected installations

All installations using `MathUtility::convertToPositiveInteger()`.

## Migration

To recover the original behavior of the deprecated method, its call can be
replaced with `max(0, $number)`. To actually convert negative numbers to
their positive counterpart, call `abs($number)`.
