 *  When specifying the fixed format, the values override the default of
 *  a ``fixed128x18``, which implies a signed 128-bit value with 18
 *  decimals of precision.
 *
 *  The alias ``fixed`` and ``ufixed`` can be used for ``fixed128x18`` and
 *  ``ufixed128x18`` respectively.
 *
 *  When a fixed format string begins with a ``u``, it indicates the field
 *  is unsigned, so any negative values will overflow. The first number
 *  indicates the bit-width and the second number indicates the decimal
 *  precision.
 *
 *  When a ``number`` is used for a fixed format, it indicates the number
 *  of decimal places, and the default width and signed-ness will be used.
 *
 *  The bit-width must be byte aligned and the decimals can be at most 80.

/**
 *  A FixedNumber represents a value over its [[FixedFormat]]
 *  arithmetic field.
 *
 *  A FixedNumber can be used to perform math, losslessly, on
 *  values which have decmial places.
 *
 *  A FixedNumber has a fixed bit-width to store values in, and stores all
 *  values internally by multiplying the value by 10 raised to the power of
 *  %%decimals%%.
 *
 *  If operations are performed that cause a value to grow too high (close to
 *  positive infinity) or too low (close to negative infinity), the value
 *  is said to //overflow//.
 *
 *  For example, an 8-bit signed value, with 0 decimals may only be within
 *  the range ``-128`` to ``127``; so ``-128 - 1`` will overflow and become
 *  ``127``. Likewise, ``127 + 1`` will overflow and become ``-127``.
 *
 *  Many operation have a normal and //unsafe// variant. The normal variant
 *  will throw a [[NumericFaultError]] on any overflow, while the //unsafe//
 *  variant will silently allow overflow, corrupting its value value.
 *
 *  If operations are performed that cause a value to become too small
 *  (close to zero), the value loses precison and is said to //underflow//.
 *
 *  For example, an value with 1 decimal place may store a number as small
 *  as ``0.1``, but the value of ``0.1 / 2`` is ``0.05``, which cannot fit
 *  into 1 decimal place, so underflow occurs which means precision is lost
 *  and the value becomes ``0``.
 *
 *  Some operations have a normal and //signalling// variant. The normal
 *  variant will silently ignore underflow, while the //signalling// variant
 *  will thow a [[NumericFaultError]] on underflow.
