Float implementation.
include Comparable with type t = floatComparison over t. compare x y returns 0 iff equal x y = 0. If x and y are not equal, it returns a negative integer iff x is lesser than y and a positive integer otherwise.
val hash : t -> intA hash function over t.
Set the precision of equal and compare for float. If the precision is p, then the floats x and y are equal iff abs(x-y) < p. By default, the precision is 1e-8 (that is 0.864 milliseconds if floats represent days).
val round : t -> intRound a float to the nearest integer.
