classes/float.pmc - Floating-point number


Float extends scalar to provide floating-point number operations.

Functions ^

void init()

Initializes the number to zero.

PMC *instantiate()

Create a new Float from the passed in argument. This is a class method, arguments are passed according to pdd03.

FLOATVAL get_number()

Returns the value of the number.

INTVAL get_integer()

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

INTVAL get_bool()

Evaluates the number as a boolean, i.e. it's true if it's not zero.

STRING *get_string()

Returns a Parrot string representation of the number.

STRING *get_repr()

void set_integer_native(INTVAL value)

void set_bool(INTVAL value)

void set_number_native(FLOATVAL value)

Sets the value of the number to value.

void set_number_same(PMC *value)

Sets the value of the number to the value of *value.

void set_string_native(STRING *value)

Sets the value of the number to the value of *value.

Note that this method morphs the number into a String.

void set_pmc(PMC *value)

Sets the value of the number to the value in *value.

void morph(INTVAL type)

Morphs the scalar to the specified type.

PMC *neg(PMC *dest)

void i_neg()

Set dest to the negated value of SELF.

INTVAL is_equal(PMC *value)

The == operation.

INTVAL cmp(PMC *value)

INTVAL cmp_num(PMC *value)

Returns the result of comparing the number with *value.

void increment()

Increments the number.

void decrement()

Decrements the number.

PMC *absolute(PMC *dest)

void i_absolute()

Sets dest to the absolute value of SELF.

void freeze(visit_info *info)

Used to archive the number.

void thaw(visit_info *info)

Used to unarchive the number.

Methods ^


Return a new PMC of the type of SELF with the cosine of SELF.
