Abstract
Systems and methods for compiling programs using condition codes and executing those programs when non-numeric values are present allow for explicit handling of non-numeric values. In addition to the conventional condition code values of positive, negative, and zero, a fourth value may be encoded, not a number (NaN) representing a non-numeric value. New condition tests are defined that explicitly account for condition code values of NaN. A compiler may produce code using the new condition tests to represent if and if-else statements. The code including the new condition tests generates deterministic results during execution when non-numeric values are present.
