`dec2base`

Converts a nonnegative integer to text in a given base (2 to 36).

Category: Language Fundamentals > Data Types

Syntax

s = dec2base(d, base)

Digits of d in base.

s = dec2base(d, base, len)

Pads with leading zeros to at least len digits.

Description

The digits are 0-9 followed by uppercase A-Z. The value is repeatedly divided by the base and the remainders form the digits, last remainder first. dec2bin and dec2hex are the same operation for base 2 and 16. The reverse is base2dec.

Input arguments

d: Nonnegative integers (up to flintmax).
base: Integer from 2 to 36.
len: Minimum number of digits.

Output arguments

s: Char array, one row per element of d, left padded with zeros to the same length.

Example

Several bases

dec2base(10, 3)
dec2base(255, 16)
dec2base(10, 2, 8)

Output

ans = '101'
ans = 'FF'
ans = '00001010'

Notes

Only a numeric base is accepted; a string of custom symbols as the base is not supported.
