Non-Decimal Ranges

Create arrays of integers from non-decimal number bases

Description

When making arrays you can specify ranges of an alternative number base by using an x or . in the end range:

a [00..ffx16]
a [00..ff.16]

All number bases from 2 (binary) to 36 (0-9 plus a-z) are supported. Please note that the start and end range are written in the target base while the base identifier is written in decimal: [hex..hex.dec]

Also note that the additional zeros denotes padding (ie the results will start at 00, 01, etc rather than 0, 1...)

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 [08..10x16]
08
09
0a
0b
0c
0d
0e
0f
10

» a [10..08x16]
10
f
e
d
c
b
a
9
8

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 [05..10x8].[0..7]
05.0
05.1
05.2
05.3
05.4
05.5
05.6
05.7
06.0
06.1
06.2
...
07.5
07.6
07.7
10.0
10.1
10.2
10.3
10.4
10.5
10.6
10.7

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"
]
