 This library provides the following public classes in the `Brick\Math` namespace:
 
-- [BigNumber](https://github.com/brick/math/blob/0.8.0/src/BigNumber.php): base class for `BigInteger`, `BigDecimal` and `BigRational`
-- [BigInteger](https://github.com/brick/math/blob/0.8.0/src/BigInteger.php): represents an arbitrary-precision integer number.
-- [BigDecimal](https://github.com/brick/math/blob/0.8.0/src/BigDecimal.php): represents an arbitrary-precision decimal number.
-- [BigRational](https://github.com/brick/math/blob/0.8.0/src/BigRational.php): represents an arbitrary-precision rational number (fraction).
-- [RoundingMode](https://github.com/brick/math/blob/0.8.0/src/RoundingMode.php): holds constants for the rounding modes.
