std/complex

The std/complex library provides the Complex struct and essential mathematical operations for working with complex numbers in Zen-C.

Overview

• Value Type: Simple struct with real and imag components.
• Operator support: Supports +, -, *, /, ==, and != via operator overloading.
• Properties: Provides methods for calculating magnitude and phase.
• Interpolation: Can be directly used in f-strings and print statements.

Usage

import "std/complex.zc"

fn main() {
    let c1 = Complex::new(3.0, 4.0);
    let c2 = Complex::new(1.0, 2.0);
    
    let sum = c1 + c2;
    let prod = c1 * c2;
    
    println "Sum: {sum}";       // Sum: 4.000000 + 6.000000i
    println "Magnitude: {c1.magnitude()}";
}

Struct Definition

struct Complex {
    real: double;
    imag: double;
}

Methods

Construction

Method	Signature	Description
new	Complex::new(r: double, i: double) -> Complex	Creates a new complex number with real component r and imaginary component i.

Access & Query

Method	Signature	Description
magnitude	magnitude(self) -> double	Returns the magnitude (absolute value) of the complex number.
phase	phase(self) -> double	Returns the phase (angle) in radians.

Operators

Operator	Method	Description
+	add	Adds two complex numbers.
-	sub	Subtracts one complex number from another.
*	mul	Multiplies two complex numbers.
/	div	Divides one complex number by another.
==	eq	Checks if two complex numbers are strictly equal.
!=	neq	Checks if two complex numbers are not equal.
{}	to_string	Enables direct string interpolation.
