Name
SPVM::Complex_2f - float Complex Type
Usage
use Complex_2f;
my $z : Complex_2f;
# Set
$z->{re} = 1.5;
$z->{im} = 2.5;
# Get
my $re = $z->{re};
my $im = $z->{im};Description
Complex_2f is a multi-numeric type to represent a float complex number.
See SPVM::Document::Language::Types about multi-numeric types.
Fields
re
has re : float;A real number.
im
has im : float;A imaginary number.
Class Methods
new
static method new : Complex_2f ($re : float = 0, $im : float = 0);
Creates a new Complex_2f multi-numeric value given the real number $re and the imaginary number $im and returns it.
new_array_from_pairs
static method new_array_from_pairs : Complex_2f[] ($pairs : float[]);
Creates a new Complex_2f array given the pairs of a real number and an imaginary number $pairs, and returns the new array.
Examples of Input:
# Input Data
[1, 2, 3, 4]
# Data of a new array
[{re => 1, im => 2}, {re => 3, im => 4}]new_array_from_re_array
static method new_array_from_re_array : Complex_2f[] ($re_array : float[]);
Creates a new Complex_2f array given real numbers $re_array, and returns the new array.
new_array_from_im_array
static method new_array_from_im_array : Complex_2f[] ($im_array : float[]);
Creates a new Complex_2f array given imaginary numbers $im_array, and returns the new array.
to_re_array
static method to_re_array : float[] ($array : Complex_2f[]);
Converts the Complex_2f array $array to the array of real numbers, and returns it.
to_im_array
static method to_im_array : float[] ($array : Complex_2f[]);
Converts the Complex_2f array $array to the array of imaginary numbers, and returns it.
to_pairs
static method to_pairs : float[] ($array : Complex_2f[]);
Converts the Complex_2f array $array to the pairs of a real number and an imaginary number, and returns it.
Examples of Output:
# Input Data
[{re => 1, im => 2}, {re => 3, im => 4}]
# Output
[1, 2, 3, 4]to_string
static method to_string : string ($z : Complex_2f);
Converts the Complex_2f multi-numeric value to a string, such as 1+2i.
Implementation:
my $string = (string)undef;
if ($z->{im} < 0) {
$string = "$z->{re}$z->{im}i";
}
else {
$string = "$z->{re}+$z->{im}i";
