bigGcd
The greatest common divisor of a and b, computed via arbitrary-precision integers -- stays exact for magnitudes far beyond ordinary 128-bit arithmetic.

Big Numbers
bigPow
base raised to a non-negative integer exponent, computed via arbitrary-precision integers -- stays an exact integer at any magnitude, unlike ordinary exponentiation which falls back to an approximate float once it outgrows native range.
base(number) --exp(number) -- non-negative integer
floor
The largest whole number <= x, exact at any size.
x(number) --
ceil
The smallest whole number >= x, exact at any size.
x(number) --
round
x rounded to the nearest whole number (halves away from zero), exact at any size.
x(number) --
trunc
x with its fractional part dropped (towards zero).
x(number) --
frac
The fractional part x - trunc(x).
x(number) --
numerator
The numerator of x in lowest terms.
x(number) --
denominator
The denominator of x in lowest terms.
x(number) --
isInteger
True if x is a whole number.
x(number) --
mixedFraction
x as a mixed number, e.g. 7/2 is "3 1/2" and -7/2 is "-3 1/2".
x(number) --
