Truth-Value Interpretation

Draft MDC Standard

7.1.4.7 Truth-value interpretation

The truth-value interpretation is a mapping from the set of all data values onto the two integer values 0 (false) and 1 (true), described by the following algorithm. Take the numeric interpretation. If the result is not "0", make it "1".

The truth-value expression tvexpr is defined to have the same syntax as expr. Its presence in a syntax definition serves to indicate that the truth-value interpretation of its value is to be taken when it is executed.

    tvexpr::= expr
