NAME

src/pmc/float.pmc - Floating-point number

DESCRIPTION

Float extends scalar to provide floating-point number operations.

Functions

void init()
Initializes the number to zero.
void destroy()
Destroy this PMC.
PMC *clone()
Make an exact copy of this PMC.
PMC *instantiate_str(STRING *rep, INTVAL flags)
Class method to construct an Integer from the string representation rep.
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.
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)
The cmp operation.
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.
