A system is disclosed for performing floating point computation in connection with numbers in a base floating point representation (such as the representation defined in IEEE Std. 754) that defines a plurality of formats, including a normalized format and a de-normalized format, using a common floating point representation that defines a unitary normalized format. The system includes a base to common representation converter, a processor and a common to base representation converter. The base to common representation converter converts numbers from the base floating point representation to the common floating point representation, so that all numbers involved in a computatoin will be expressed in the unitary normalized format. The processor is configured to perform a mathematical operation of at least one predetermined type in connection with the converted numbers generated by the base to common representation converter to generate a floating point result in the common representation. The common to base representation converter converts numbers from the common floating point representation selectively to either the normalized or de-normalized format of the base representation.
