fix coverage

The use of strconv.FormatFloat causes a string allocation,
by setting aside a reusable buffer and using strconv.AppendFloat
this can be avoided.

Before:
BenchmarkRespond-4           300           5392189 ns/op          618936 B/op      20010 allocs/op

After:
BenchmarkRespond-4           300           4713746 ns/op          139744 B/op         10 allocs/op

This benchmark is using a custom encoder that calls WriteFloat64 20k
times, which is the bulk of the work.
