## Detailed Description

A definition for numerical arguments.

These arguments allows numerical values. The value can be restricted to real or rational numbers (defaults to allow all numbers, including complex), and a max and/or min value.

## Member Function Documentation

virtual bool NumberArgument::subtest | ( | MathStructure & | value,
|  | const EvaluationOptions & | eo |
| ) |  |  | const`[protected, virtual]`

This function is called from Argument::test() and performs validation specific to the argument definition type. Should be reimplemented by all subclasses.

Parameters:

  | value | Value to test.
  | eo | Evaluation options to use if the value needs to be evaluated.

Returns:
  true if the value is valid for the argument definition.

Reimplemented from Argument.

virtual string NumberArgument::subprintlong | ( |  | ) | const`[protected, virtual]`

This function is called from Argument::printlong() and returns description specific the argument definition type. Should be reimplemented by all subclasses. For example IntegerArgument::subprintlong() might return "an integer" and Argument::printlong() might append " that fulfills the condition: even(\x)".

Returns:
  Long description.

Reimplemented from Argument.

virtual void NumberArgument::set | ( | const Argument * | arg | ) | `[virtual]`

Sets the argument to a copy of an argument definition.

Parameters:

  | arg | Argument to copy.

Reimplemented from Argument.

virtual Argument* NumberArgument::copy | ( |  | ) | const`[virtual]`

Returns a copy of the argument definition.

Returns:
  A copy.

Reimplemented from Argument.

virtual string NumberArgument::print | ( |  | ) | const`[virtual]`

Resturns a short description of the argument definition. Ex. "number" for NumberArgument.

Returns:
  Short description.

Reimplemented from Argument.

virtual int NumberArgument::type | ( |  | ) | const`[virtual]`

Returns the type of the argument, corresponding to which subclass the object belongs to.

Returns:
  ArgumentType.

Reimplemented from Argument.
