If you are interested in the two subjects listed I would appreciate
your reaction to my first draft of comments on the proposed ANSI C standard.
Reply by mail (rather than posting!)
and I will send you the ?roff source. Here's an abstract:
The proposed C standard suffers numerical
shortcomings - many inherited from its precursors
- in the areas of expression evaluation and
floating-point exception handling, particularly in
the library of elementary transcendental func-
tions. The following comments are included:
Comment #1, Section 3.2.1.4: round conversions between floating types
Comment #2, Section 3.4: facilitate deferral of constant expression evaluation
Comment #3, Section 4.7: SIGFPE means floating point
Comment #4, Section 4.9.6.2: scanf requires pushback > 1
Comment #5, Section 4.10.2: require two random number generators
Comment #6, Section 3.3.3.3: respect parentheses in expression evaluation
Comment #7, Section 2.2.4.2: <float.h> has too many names, not enough information
Comment #8, Section 4.9.6: printf/scanf duality for non-model numbers
Comment #9, Section 4.10.1.4: strtod/atof are mathematical functions
Comment #10, Section 4.13.2: standard functions are operators
Comment #11, Section 4.5: make numerical exception handling uniform
Comment #12, Section 4.5: specific mathematical library functions
