According to one general aspect, an apparatus may include a key selector configured to select a personality key from at least a portion of an input value. The apparatus may include a sparse look-up table configured to determine a portion of a result based upon the personality key and a prior remainder. The apparatus may include an adder configured to compute a current remainder based upon, at least, the input value, and the portion of the result. The apparatus may be configured to iteratively compute current remainders and portions of the result until either the current remainder is zero, or a predefined level of precision is reached.
