Bencher::Scenario::MathBigFloat::Add - Benchmark adding 0.5 100 times
This document describes version 0.001 of Bencher::Scenario::MathBigFloat::Add (from Perl distribution Bencher-Scenarios-MathBigFloat), released on 2017-12-09.
To run benchmark with default option:
% bencher -m MathBigFloat::Add
To run module startup overhead benchmark:
% bencher --module-startup -m MathBigFloat::Add
For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
bencher --help
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
Version numbers shown below are the versions used when running the sample benchmark.
Math::BigFloat 1.999808

Code template:
my $n = Math::BigFloat->new("0"); my $m = Math::BigFloat->new("0.5"); for (1..100) { $n->badd($m) } $n->bstr
native (perl_code)
my $n = 0; for (1..100) { $n += 0.5 } $n
