Fixnum to Bignum promotion In Ruby, Fixnum math can promote to Bignum when the result is out of Fixnum's range. On implementations that use tagged pointers to represent Fixnum (MRI, Rubinius, MacRuby), the Fixnum range is somewhat less than the base CPU bits (32/64). On JRuby, Fixnum is always a straight 64-bit signed value. This promotion is a performance concern for a couple reasons: Every math operation that returns a new Fixnum must be range-checked. This slows all Fixnum operations. It is difficult (if not impossible) to predict whether a Fixnum math opera...
