128-bit complex number.
var Complex128 = require( '@stdlib/complex/float64' );128-bit complex number constructor, where real and imag are the real and imaginary components, respectively.
var z = new Complex128( 5.0, 3.0 );
// returns <Complex128>Size (in bytes) of each component.
var nbytes = Complex128.BYTES_PER_ELEMENT;
// returns 8Size (in bytes) of each component.
var z = new Complex128( 5.0, 3.0 );
var nbytes = z.BYTES_PER_ELEMENT;
// returns 8Length (in bytes) of a complex number.
var z = new Complex128( 5.0, 3.0 );
var nbytes = z.byteLength;
// returns 16A Complex128 instance has the following properties...
A read-only property returning the real component.
var z = new Complex128( 5.0, 3.0 );
var re = z.re;
// returns 5.0A read-only property returning the imaginary component.
var z = new Complex128( 5.0, -3.0 );
var im = z.im;
// returns -3.0These methods do not mutate a Complex128 instance and, instead, return a complex number representation.
Returns a string representation of a Complex128 instance.
var z = new Complex128( 5.0, 3.0 );
var str = z.toString();
// returns '5 + 3i'
z = new Complex128( -5.0, -3.0 );
str = z.toString();
// returns '-5 - 3i'Returns a JSON representation of a Complex128 instance. JSON.stringify() implicitly calls this method when stringifying a Complex128 instance.
var z = new Complex128( 5.0, -3.0 );
var o = z.toJSON();

- Both the real and imaginary components are stored as double-precision floating-point numbers.
