They can be used to obtain more realistic data on the real-world performance of big.Float printing.

In addition to the DecimalConversion benchmark, that exercises the
String method of the internal decimal type on a range of small shifts,
add a few benchmarks for the big.Float String method. They can be used
to obtain more realistic data on the real-world performance of

math/big: factored out an internal accessor method (cleanup), added benchmark 2015-09-23T20:25:59+00:00 Robert Griesemer gri@golang.org 2015-09-23T17:05:44+00:00 59a6ba56347cb83c7e84e8d1eb9fbcd98ec99b59 Current result of DecimalConversion benchmark (for future reference): BenchmarkDecimalConversion-8 10000 204770 ns/op Measured on Mac Mini (late 2012) running OS X 10.10.5, 2.3 GHz Intel Core i7, 8 GB 1333 MHz DDR3. Also: Removed comment suggesting to implement decimal by representing digits as numbers 0..9 rather than ASCII chars '0'..'9' to avoid repeated +/-'0' operations. Tried and it appears (per above benchmark) that the +/-'0' operations are neglibile but the addition conversion passes around it are not and that it makes things significantly slower.
