This applies in section 2.6 on Numerical Models, in the treatment of section 3.3 Number types (including subtypes), and in the definitions of operators and functions where there is something to be said for the quality with which results are approximated.
Test case for TAN() currently is:
with an expected result of:
However a test case for LOG() is:
with expected result of 3 (with no epsilon).
Is this intentional? I suspect that few implementations are going to be optimized to produce exact results here.
Do we have a general rule here? Shouldn't it be that any function that has a domain of real numbers should be allowed an epsilon on test results? And only functions whose domain consists of the integers should be required to give exact results?
