isFloat64ndarrayLike
Test if a value is an ndarray-like object containing double-precision floating-point numbers.
Usage
var isFloat64ndarrayLike = require( '@stdlib/assert/is-float64ndarray-like' ); isFloat64ndarrayLike( value )
Tests if a value is an ndarray-like object whose underlying data type is float64.
var Float64Array = require( '@stdlib/array/float64' ); var ndarray = require( '@stdlib/ndarray/ctor' ); var arr = ndarray( 'float64', new Float64Array( [ 0, 0, 0, 0 ] ), [ 2, 2 ], [ 2, 1 ], 0, 'row-major' ); var bool = isFloat64ndarrayLike( arr ); // returns true Examples
var ndarray = require( '@stdlib/ndarray/ctor' ); var Float64Array = require( '@stdlib/array/float64' ); var isFloat64ndarrayLike = require( '@stdlib/assert/is-float64ndarray-like' ); var buffer = new Float64Array( [ 0, 0, 0, 0 ] ); var arr = ndarray( 'float64', buffer, [ 2, 2 ], [ 2, 1 ], 0, 'row-major' ); var out = isFloat64ndarrayLike( arr ); // returns true out = isFloat64ndarrayLike( [ 1, 2, 3, 4 ] ); // returns false out = isFloat64ndarrayLike( {} ); // returns false out = isFloat64ndarrayLike( null ); // returns false
