ABSTRACT:
An apparatus for storing data in a computer memory, the number originating from one of a plurality of floating point data formats. Each data format from which the number originates has a first exponent bias and a minimum exponent value. The number has a first exponent and an unbiased exponent value, the unbiased exponent value equal to the difference between the first exponent and the first exponent bias. The number also has a sign and a significand. The apparatus for storing the number in computer memory consists of at least one sign bit and a significand having an explicit integer bit, the explicit integer bit having a first predetermined value when the number is normal and having a second predetermined value when the number is denormal. The apparatus also has a second exponent with a second exponent bias, the second exponent equal to the sum of the unbiased exponent value and the second exponent bias when the number is normal, the second exponent equal to the sum of the minimum exponent value and the second exponent bias when the number is denormal.
