Create an array filled with NaNs and having a specified length.
var nans = require( '@stdlib/array/nans' );Creates an array filled with NaNs and having a specified length.
var arr = nans( 2 );
// returns <Float64Array>[ NaN, NaN ]The function recognizes the following data types:
float64: double-precision floating-point numbers (IEEE 754)float32: single-precision floating-point numbers (IEEE 754)complex128: double-precision complex floating-point numberscomplex64: single-precision complex floating-point numbersgeneric: generic JavaScript values
By default, the output array data type is float64 (i.e., a typed array). To specify an alternative data type, provide a dtype argument.
var arr = nans( 2, 'float32' );
// returns <Float32Array>[ NaN, NaN ]- For complex number arrays, each element of the returned array has a real component equal to
NaNand an imaginary component equal toNaN.
var dtypes = require( '@stdlib/array/typed-float-dtypes' );
var nans = require( '@stdlib/array/nans' );
// Get a list of array data types:
var dt = dtypes();
// Generate filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
arr = nans( 4, dt[ i ] );
console.log( arr );
