interpreter-binary-perf
Brief performance testing of binary/decimal conversion functions in different scripting interpreters.
Test conditions
Performed under bit noisy conditions (web browser + media player open, etc).
Each test was run 3x, reporting the best time
All tests are single-threaded.

Binary to decimal
- Use 511 as sample value to bypass 8-bit interning
| Language | Time(real) | Command |
|---|---|---|
