API

convertFromBaseNToDecimal(numberToConvert: string, fromBase: number): number

Converts a number in base N to a decimal number. numberToConvert needs to be a string because when N is greater than or equal to 10, we need to use letters.

baseConverter.convertFromBaseNToDecimal('101', 2); //returns 5
baseConverter.convertFromBaseNToDecimal('ABC', 16); //returns 274
baseConverter.convertFromBaseNToDecimal('101.11', 2); //returns 5.75

convertFromDecimalToBaseN(numberToConvert: number, toBase: number, precision = 2): string

Converts a decimal number to a number in base N.

baseConverter.convertFromDecimalToBaseN(173, 16); //returns 'AD'
baseConverter.convertFromDecimalToBaseN(17.6, 3); //returns '122.12'

convert(numberToConvert: string, convertOptions: object): string

Converts a number from base N to a number in base M. The convertOptions contains the following properties:

convertOptions = {
  fromBase: number;
  toBase: number;
  precision: number = 2;
}

baseConverter.convert('78', { fromBase: 11, toBase: 6 }); // returns '221'
baseConverter.convert('45.5', { fromBase: 14, toBase: 2 }); // returns '111101.01'
