Package-level declarations

Class representing a complex number (re + imj), where j == sqrt(-1). Yes, j, not i, because I'm an electrical engineer, and 'i' stands for current (Ohm's Law: V = IR).

Sample code to show in KDoc.

Just like Complex.close; returns true if a Double is within epsilon of another.

Expands the receiver to Complex and divides it by other

Turns the (radian) angle theta into the complex number at that angle, with unit magnitude. Thanks to Leonhard Euler for discovering this property: e^(jθ) = cos θ + j sin θ

Format a double, optionally with another char (like i or j). If char is the default NUL (ASCII 0), it is not part of the result string.

Creates a "pure imaginary" number from receiver * sqrt(-1).

Expands the receiver to Complex and subtracts other from it.

Expands the receiver to Complex and adds other to it.

Round to decimals places. If decimals is negative, rounds to the desired power of 10; so round(-2) will round to the nearest hundred.

Returns the square of the receiver.

Takes the square root, as a Complex number. Works just fine with negative real numbers. Does not interfere with Double.sqrt(x: Double), since the signature is different.

Expands the receiver to Complex and multiplies it by other

Creates a "pure real" Complex number from the receiver
