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[10]   # 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.
