Syntax

decode(s: string): number

console.log(bs16.decode('1f')) // output 31

Syntax

add(s1: string, s2: string): string

console.log(bs16.add('1f', '1f')) // output 3e

Subtract

subtract method will return base n string. i.e, subtraction of given two base n strings

Note By default subtract will return absolute value

subtract(s1: string, s2: string, abs=true): string

Note: subtract method "abs" parameter defaults to true

console.log(bs16.subtract('1ff', '10')) // output 1ef

compare method will return 1|0|-1

Syntax

compare(s1: string, s2:string): number

Example:

s1 > s2 => 1

s1 = s2 => 0

s1 < s2 => -1

console.log(bs16.compare('1ff', '10')) // output 1
