# Types::Common::Numeric

## Status

This module is covered by the Type-Tiny stability policy .

## Description

A drop-in replacement for MooseX::Types::Common::Numeric .

### Types

The following types are similar to those described in MooseX::Types::Common::Numeric .

• PositiveNum
• PositiveOrZeroNum
• PositiveInt
• PositiveOrZeroInt
• NegativeNum
• NegativeOrZeroNum
• NegativeInt
• NegativeOrZeroInt
• SingleDigit

``` SingleDigit ``` interestingly accepts the numbers -9 to -1; not just 0 to 9.

This module also defines an extra pair of type constraints not found in MooseX::Types::Common::Numeric .

• IntRange[`min, `max]

Type constraint for an integer between min and max. For example:

``  IntRange[1, 10]``

The maximum can be omitted.

``  IntRange   # at least 10``

The minimum and maximum are inclusive.

• NumRange[`min, `max]

Type constraint for a number between min and max. For example:

``  NumRange[0.1, 10.0]``

As with IntRange, the maximum can be omitted, and the minimum and maximum are inclusive.

Exclusive ranges can be useful for non-integer values, so additional parameters can be given to make the minimum and maximum exclusive.

``````  NumRange[0.1, 10.0, 0, 0]  # both inclusive
NumRange[0.1, 10.0, 0, 1]  # exclusive maximum, so 10.0 is invalid
NumRange[0.1, 10.0, 1, 0]  # exclusive minimum, so 0.1 is invalid
NumRange[0.1, 10.0, 1, 1]  # both exclusive``````

Making one of the limits exclusive means that a ``` < ``` or ``` > ``` operator will be used instead of the usual ``` <= ``` or ``` >= ``` operators.
