void morph(INTVAL type)

Morphs the scalar to the specified type.

STRING *name()

Return the string "number".

INTVAL get_integer()

Returns an integer representation of the number (by casting).

FLOATVAL get_number()

Returns the value of the number.

STRING *get_string()

Returns a Parrot string representation of the number.
