eq

  eq(Any $arg1) : NumObject

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

eq example

  # given $undef

  $undef->eq; # exception thrown

ge

  ge(Any $arg1) : NumObject

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

ge example

  # given $undef

  $undef->ge; # exception thrown

gt

  gt(Any $arg1) : NumObject

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

gt example

  # given $undef

  $undef->gt; # exception thrown

le

  le(Any $arg1) : NumObject
