Abstract
A computer program product for converting from a first floating point format to a second floating point format, each floating point format having an associated base value and being represented by a significand value and a exponent value, comprising an executable algorithm to perform the steps of: determining the second exponent value by multiplying the first exponent value by a predefined constant and taking the integer portion of the result, the predefined constant being substantially equivalent to the logarithm of the first base value divided by the logarithm of the second base value; determining a bias value substantially equivalent to the second base value raised to the second exponent value divided by the first base value raised to the first exponent value; and determining the second significand value by multiplying the first significand value by the bias value.
