include bench.e include euslibs_math.e include math.e sequence p p = {} set_bench_timer(3) -- want 3-second tests add_test("Standard Lib ceil()",routine_id("ceil")) add_test("EusLibs ceil()",routine_id("euslibs_ceil")) set_bench_parameter( {{3.2,-4.7,6.8,19.23,21}} ) run_tests() -- first test with 5 elements for t=1 to 10000 do p &= rand(10000) / 100 end for set_bench_parameter( {p} ) run_tests() -- second test with 10000 elements
Typical results from running a benchmark: Final Results: EusLibs ceil() - 2232042 <-- Fastest! Standard Lib ceil() - 2159694 <-- Slower by 3.241337% The EusLibs ceil() is just -floor(-a). I guess floor() is a Speedy Gonzalez, eh? :)

Update every morning. ;) Your new standard lib code is conflicting with my EusLibs, so I'm making this announcement: as Jeremy updates the standard libs, I'm going to REMOVE the CORRESPONDING funcs/procs from EusLibs. All opposed, say NAY.

All opposed, say NAY. I wonder if this should be done at the point that 3.2 is released? For instance, this has not happened yet, but, say someone add's a function ceil() and then it's decided that it should not be part of the standard library and 5 days later removed. You would have deleted code. I wonder how many people are keeping up with and using SVN copy is production? I would hope no one. -- Jeremy Cowgar http://jeremy.cowgar.com
