NAME

classes/float.pmc - Floating-point number

DESCRIPTION

Float extends scalar to provide floating-point number operations.

Methods

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_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.

void add(PMC *value, PMC *dest)

Adds *value to the number and returns the result in *dest.

void add_int(INTVAL value, PMC *dest)

Adds value to the number and returns the result in *dest.

void add_float(FLOATVAL value, PMC *dest)

Adds value to the number and returns the result in *dest.

void subtract(PMC *value, PMC *dest)

Subtracts *value from the number and returns the result in *dest.

void subtract_int(INTVAL value, PMC *dest)

Subtracts value from the number and returns the result in *dest.

void subtract_float(FLOATVAL value, PMC *dest)

Subtracts value from the number and returns the result in *dest.

void multiply(PMC *value, PMC *dest)

Multiplies the number by *value and returns the result in *dest.

void multiply_int(INTVAL value, PMC *dest)

Multiplies the number by value and returns the result in *dest.

void multiply_float(FLOATVAL value, PMC *dest)

Multiplies the number by value and returns the result in *dest.

void divide(PMC *value, PMC *dest)

Divides the number by *value and returns the result in *dest.

void divide_int(INTVAL value, PMC *dest)

void divide_float(FLOATVAL value, PMC *dest)

Divides the number by value and returns the result in *dest.

void cmodulus(PMC *value, PMC *dest)

Calculates the value of the number C-style mod *value and returns the result in *dest.

void cmodulus_float(FLOATVAL value, PMC *dest)

void cmodulus_int(INTVAL value, PMC *dest)

Calculates the value of the number C-style mod value and returns the result in *dest.

void modulus(PMC *value, PMC *dest)

Calculates the value of the number mod *value and returns the result in *dest.

void modulus_float(FLOATVAL value, PMC *dest)

void modulus_int(INTVAL value, PMC *dest)

Calculates the value of the number mod value and returns the result in *dest.

void neg(PMC *dest)

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.

void 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.
