formatBase

Writes a whole number as text in a base from 2 to 36, with optional zero padding.

Details #

formatBase(number, base, digits?) takes two or three arguments and returns text.

number is cut to a whole number (decimals are dropped, not rounded).
base is 2 to 36. Letters above 9 come back in capitals, so base 16 gives FF.
digits pads with zeros on the left to at least that many characters. Without it there is no padding.

A negative number keeps its minus sign in front of the padding: formatBase(-5, 2, 4) is -0101. The result is text; use hex, oct or bin to turn it back into a number.

Parameters #

Takes 2 to 3 arguments. {{ formatBase(text, b, c?) }}

Examples #

formatBase(255, 16)

→ FF

formatBase(5, 2, 8)

→ 00000101

formatBase(n, 16, 6)

→ 001000

Sample variable	Value
`n`	`4096`

Gotchas #

A base below 2 or above 36 stops the step: formatBase() works in bases 2 to 36.
Anything that isn't a number is an error: formatBase() needs a number, got text.
