Abstract
A method for storage for complex numbers that employs a shared exponent field is disclosed. Rather than each floating point component of an complex number having its own distinct signed mantissa and exponent fields, each component includes a distinct signed mantissa field and shares an exponent field, thereby increasing the possible size of each distinct signed mantissa field by as much as one half the number of bits formerly employed to store a single distinct exponent field.
