Benchmark
How fast is faiNumber-Fortran?
The below are benchmark results for faiNumber-Fortran(Version 1n.0.0.f) comparing to the read() method of Fortran. Each test ran 3 times and the average result from all 3 runs is used as the result. Results are in seconds with 3 decimal placement. For the result, the lower is the better.
Although this benchmark test was run as a build for f2018, other versions of Fortran(from gfortran's -std=legacy to f2003) were tested lightly and did show to operate at almost similar or as the same speed as the benchmark score below.
