Decimal Ranges

Create arrays of decimal integers

Description

This document describes how to create arrays of decimals using mkarray (a et al).

Please refer to a (mkarray) for more detailed usage of mkarray.

Usage

a: [start..end] -> <stdout>
a: [start..end,start..end] -> <stdout>
a: [start..end][start..end] -> <stdout>

All usages also work with ja and ta as well, eg:

ja: [start..end] -> <stdout>
ta: data-type [start..end] -> <stdout>

You can also inline arrays with the %[] syntax, eg:

%[start..end]

Examples

» a [1..3]
1
2
3

» a [3..1]
3
2
1

» a [01..03]
01
02
03

Floating Point Numbers

If you do need a range of fixed floating point numbers generated then you can do so by merging two decimal integer ranges together. For example

» a [0..5].[0..9]
0.0
0.1
0.2
0.3
0.4
0.5
0.6
0.7
0.8
0.9
1.0
1.1
1.2
1.3
...
4.8
4.9
5.0
5.1
5.2
5.3
5.4
5.5
5.6
5.7
5.8
5.9

Everything Is A String

Please note that all arrays are created as strings. Even when using typed arrays such as JSON (ja).

» ja [0..5]
[
    "0",
    "1",
    "2",
    "3",
    "4",
    "5"
]
