Warming up --------------------------------------

          Float#to_s   247.825k i/100ms

     FastFloatString     1.052M i/100ms

Calculating -------------------------------------

          Float#to_s      2.549M (± 0.7%) i/s -     12.887M in   5.056726s

     FastFloatString     10.472M (± 0.7%) i/s -     52.611M in   5.024229s

Comparison:

     FastFloatString: 10472007.8 i/s

          Float#to_s:  2548594.9 i/s - 4.11x  slower
