Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.

Return the real component of a single-precision complex floating-point number.
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!

npm install @stdlib/complex-realf
var realf = require( '@stdlib/complex-realf' );
Returns the real component of a single-precision complex floating-point number.
var Complex64 = require( '@stdlib/complex-float32' );
var z = new Complex64( 5.0, 3.0 );
var re = realf( z );
// returns 5.0
var Complex64 = require( '@stdlib/complex-float32' );
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var realf = require( '@stdlib/complex-realf' );
var re;
var im;
var z;
var i;
for ( i = 0; i < 100; i++ ) {
re = round( (randu()*100.0) - 50.0 );
im = round( (randu()*50.0) - 25.0 );
z = new Complex64( re, im );
console.log( 'realf(%s) = %d', z.toString(), realf( z ) );
}
#include "stdlib/complex/realf.h"
Returns the real component of a single-precision complex floating-point number.
#include "stdlib/complex/float32.h"
stdlib_complex64_t z = stdlib_complex64( 5.0f, 2.0f );
// ...
float re = stdlib_realf( z );
// returns 5.0f
The function accepts the following arguments:
[in] stdlib_complex64_t
single-precision complex floating-point number.float stdlib_realf( const stdlib_complex64_t z );
#include "stdlib/complex/realf.h"
#include "stdlib/complex/float32.h"
#include <stdio.h>
int main( void ) {
const stdlib_complex64_t x[] = {
stdlib_complex64( 5.0f, 2.0f ),
stdlib_complex64( -2.0f, 1.0f ),
stdlib_complex64( 0.0f, -0.0f ),
stdlib_complex64( 0.0f/0.0f, 0.0f/0.0f )
};
int i;
for ( i = 0; i < 4; i++ ) {
printf( "realf(v) = %f\n", stdlib_realf( x[ i ] ) );
}
}
