var oneTo = require( '@stdlib/array-one-to' );
Generates a linearly spaced numeric array whose elements increment by 1
starting from one.
var arr = oneTo( 5 );
// returns <Float64Array>[ 1.0, 2.0, 3.0, 4.0, 5.0 ]
If n == 0
, the function returns an empty array.
var arr = oneTo( 0 );
// returns <Float64Array>[]
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 numbersint32
: 32-bit two's complement signed integersuint32
: 32-bit unsigned integersint16
: 16-bit two's complement signed integersuint16
: 16-bit unsigned integersint8
: 8-bit two's complement signed integersuint8
: 8-bit unsigned integersuint8c
: 8-bit unsigned integers clamped to 0-255
generic
: generic JavaScript valuesBy 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 = oneTo( 5, 'int32' );
// returns <Int32Array>[ 1, 2, 3, 4, 5 ]
