About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

parseComplex128

Parse a string representation of a 128-bit complex number.

Installation

npm install @stdlib/complex-float64-parse

Usage

var parseComplex128 = require( '@stdlib/complex-float64-parse' );

parseComplex128( str )

Parse a string representation of a 128-bit complex number.

var real = require( '@stdlib/complex-float64-real' );
var imag = require( '@stdlib/complex-float64-imag' );

var str = '5 + 3i';

var z = parseComplex128( str );
// returns <Complex128>

var re = real( z );
// returns 5.0

var im = imag( z );
// returns 3.0

For details on the string format, see Complex128.

Examples

var parseComplex128 = require( '@stdlib/complex-float64-parse' );
var isComplex128 = require( '@stdlib/assert-is-complex128' );
var real = require( '@stdlib/complex-float64-real' );
var imag = require( '@stdlib/complex-float64-imag' );

var str = '1e3 - 2.75i';

var z = parseComplex128( str );
var bool = isComplex128( z );
// returns true

bool = ( real( z ) === 1e3 );
// returns true

bool = ( imag( z ) === -2.75 );
// returns true
