Rajan: Different compilers will have different costs associated
with adding in the redundant types. What is expensive for one (ex. New
types) may be cheap for another compiler, while the inverse may be true
for things like suffixes.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Jim: Testing is costly though for new functions.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Fred: The Fortran standard has parts specifically to interact with
C and they would like real functions.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Jim: Perhaps we can simplify tgmath to say it can use any function
that is wide enough without needing to give an algorithm for it. Joseph
pointed out issues with the integer arguments. It could lose precision
on integral arguments in unpredictable ways.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Fred: Perhaps disallow integers to be tgmath functions.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Jim: That would break existing code, but is possible.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Jim: Should this attempt be abandoned? No bandwidth to change directions.</span><br><span style=" font-size:10pt;font-family:sans-serif">
Jim: Should the annex change from referring to type to referring
to format? Types seems a better name for it.</span><br><span style=" font-size:10pt;font-family:sans-serif">
David: We used format to allow language standards to use types.</span><br><span style=" font-size:10pt;font-family:sans-serif">
