Abstract
A set of reliable floating-point arithmetic algorithms for Berger encoded operands is presented. Closed-form equations are derived for floating-point addition, subtraction, multiplication and division. Given the IEEE floating-point number standard, the redundancy requirements of the proposed scheme are 39.47% for addition/subtraction, 45.65% for multiplication, and 45.44% for division of single precision numbers. The scheme uses only 16.14% for addition/subtraction, 36.44% for multiplication and 36.02% for division of double-precision numbers
