Compute the sum of the absolute values of the real and imaginary components of a single-precision complex floating-point number.
npm install @stdlib/blas-base-scabs1We 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!

> Compute the sum of the [absolute values][absolute-value] of the real and imaginary components of a single-precision [complex][@stdlib/complex/float32/ctor] floating-point number.
``bash`
npm install @stdlib/blas-base-scabs1
`javascript`
var scabs1 = require( '@stdlib/blas-base-scabs1' );
#### scabs1( z )
Computes the sum of the [absolute values][absolute-value] of the real and imaginary components of a single-precision [complex][@stdlib/complex/float32/ctor] floating-point number.
`javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var y = scabs1( new Complex64( 5.0, -3.0 ) );
// returns 8.0
`
`javascript
var Complex64 = require( '@stdlib/complex-float32-ctor' );
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' );
var scabs1 = require( '@stdlib/blas-base-scabs1' );
var c;
var i;
for ( i = 0; i < 100; i++ ) {

}

*
`c`
#include "stdlib/blas/base/scabs1.h"
#### c_scabs1( c )
Computes the sum of the [absolute values][absolute-value] of the real and imaginary components of a single-precision [complex][@stdlib/complex/float32/ctor] floating-point number.
`c
#include "stdlib/complex/float32/ctor.h"
const stdlib_complex64_t c = stdlib_complex64( 5.0f, -3.0f );
float y = c_scabs1( c );
// returns 8.0f
`
The function accepts the following arguments:
- c: [in] stdlib_complex64_t complex number.
`c`
float c_scabs1( const stdlib_complex64_t c );
