Abstract: A method and system for processing a set of ‘k’ floating point numbers to perform addition and/or subtraction is disclosed. Each floating-point number comprises a mantissa (mi) and an exponent (ei). The method comprises receiving the set of ‘k’ floating point numbers in a first format, each floating-point number in the first format comprising a mantissa (mi) with a bit-length of ‘b’ bits. The method further comprises creating a set of ‘k’ numbers (yi) based on the mantissas of the ‘k’ floating-point numbers, the numbers having a bit-length of ‘n’ bits obtained by adding both extra most-significant bits and extra least-significant bits to the bit length ‘b’ of the mantissa (mi).
