1. A method of controlling a range of representable numbers, the method comprising:
receiving, by a processor, a floating point value represented by an exponent and a mantissa, each represented by a predetermined number of bits;
determining, by the processor, a bit configuration of the exponent and the mantissa of the floating point value based on a value of a most significant bit of the exponent of the floating point value; and
determining, by the processor, a constant required for calculation of the floating point value based on the determined bit configuration of the exponent.
