Synopsis

Positional numeral systems

class PositionalSystem s where Source #

Positional numeral system.

Methods

systemName :: s -> String Source #

The name of the system (e.g. "binary", "decimal").

radixIn :: Num α => s -> α Source #

The radix of the system.

isDigitIn :: s -> Char -> Bool Source #

Test if a character is a digit.

isNzDigitIn :: s -> Char -> Bool Source #

Test if a character is a non-zero digit.

fromDigitIn :: Num α => s -> Char -> Maybe α Source #

Map digits to the corresponding numbers. Return Nothing on other inputs.

fromNzDigitIn :: Num α => s -> Char -> Maybe α Source #

Map non-zero digits to the corresponding numbers. Return Nothing on other inputs.

unsafeFromDigitIn :: Num α => s -> Char -> α Source #

Map digits to the corresponding numbers. No checks are performed.

intToDigitIn :: s -> Int -> Char Source #

Map Int values to the corresponding digits. Inputs must be non-negative and less than the radix.

Arguments

:: (PositionalSystem s, Real α, Printer p) 
=> s 
-> p

Prefix for negative values

-> p

Zero printer

-> p

Prefix for positive values

-> p

Numerator/denominator separator

-> Optional

Whether to print invisible denominators

-> α
