Export assignment csignum

• csignum(out: ArrayLike<number>, re: number, im: number): ArrayLike<number>
• csignum(re: number, im: number): ArrayLike<number>

• Evaluates the signum function of a complex number.

  Parameters

  • out: ArrayLike<number>

    output array

  • re: number

    real component

  • im: number

    imaginary component

  Returns ArrayLike < number >

  real and imaginary components

  Example

  var Float32Array = require( `@stdlib/array/float32` );
  
  var out = new Float32Array( 2 );
  
  var v = csignum( out, -4.2, 5.5 );
  // returns <Float32Array>[ -0.6069136033622302, 0.79476781392673 ]
  
  var bool = ( v === out );
  // returns true

• Evaluates the signum function of a complex number.

  Parameters

  • re: number

    real component

  • im: number

    imaginary component

  Returns ArrayLike < number >

  real and imaginary components

  Example

  var v = csignum( -4.2, 5.5 );
  // returns [ -0.6069136033622302, 0.79476781392673 ]

  Example

  var v = csignum( 0.0, 0.0 );
  // returns [ 0.0, 0.0 ]

  Example

  var v = csignum( NaN, NaN );
  // returns [ NaN, NaN ]
