The longest numbers we have to represent are the smallest denormals. Their decimal mantissa is not longer than 5^1100. Taking into account some extra size for in-place operations, 800 digits are enough. This saves time used for zero intiialization of extra bytes. old ns/op new ns/op delta strconv_test.BenchmarkAtof64Decimal 521 334 -35.9% strconv_test.BenchmarkAtof64Float 572 391 -31.6% strconv_test.BenchmarkAtof64FloatExp 10242 10036 -2.0% strconv_test.BenchmarkAtof64Big 4229 4029 -4.7% strconv_test.BenchmarkFormatFloatDecimal 1396 934 -33.1% strconv_test.BenchmarkFormatFloat 4295 3341 -22.2% strconv_test.BenchmarkFormatFloatExp 12035 11181 -7.1% strconv_test.BenchmarkFormatFloatBig 4213 3229 -23.4% strconv_test.BenchmarkAppendFloatDecimal 1031 600 -41.8% strconv_test.BenchmarkAppendFloat 3971 3044 -23.3% strconv_test.BenchmarkAppendFloatExp 11699 11003 -5.9% strconv_test.BenchmarkAppendFloatBig 3836 2915 -24.0% R=golang-dev, bradfitz, rsc CC=golang-dev, remy https://golang.org/cl/54910643a2dec02
