Abstract
The present application is directed to determining attributes for results of arithmetic operations with fixed-point numbers. An indication is received of possible word lengths to store digits representing a result of an arithmetic operation with fixed-point numbers. An indication is received of how a placement of a radix point will be determined in the digits representing the result of the arithmetic operation with fixed-point numbers. When calculating the fixed-point arithmetic operation, one of the possible word lengths is employed for storing the digits representing the result of the fixed-point arithmetic operation. A placement of a radix point in the digits is based on the received indication of how the radix point is to be determined. Growth rate for a number of digits in a result of a series of arithmetic calculations is less than N, where N is equal to the number of arithmetic operations performed.
