isComplexLike

Test if a value is a complex number-like object.

Usage

var isComplexLike = require( '@stdlib/assert/is-complex-like' );

isComplexLike( value )

Tests if a value is a complex number-like object.

var Complex128 = require( '@stdlib/complex/float64/ctor' );
var Complex64 = require( '@stdlib/complex/float32/ctor' );

var x = new Complex128( 1.0, 3.0 );
var bool = isComplexLike( x );
// returns true

x = new Complex64( 3.0, 1.0 );
bool = isComplexLike( x );
// returns true

x = {
    're': 1.0,
    'im': -1.0
};
bool = isComplexLike( x );
// returns true

Notes

  • A complex number-like object is defined as an object having the following properties assigned to numeric values:

    • re: real component.
    • im: imaginary component.

Examples

var Complex64 = require( '@stdlib/complex/float32/ctor' );
var Complex128 = require( '@stdlib/complex/float64/ctor' );
var isComplexLike = require( '@stdlib/assert/is-complex-like' );

var out = isComplexLike( new Complex64( 2.0, 2.0 ) );
// returns true

out = isComplexLike( new Complex128( 3.0, 1.0 ) );
// returns true

out = isComplexLike( { 're': 1.0, 'im': -1.0 } );
// returns true

out = isComplexLike( {} );
// returns false

out = isComplexLike( null );
// returns false
