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? :)

I've learned my lesson. 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.
