f39378d939 Fix decoding of .0
Since trailing 0 digits after the decimal point are trimmed, intString
becomes an empty string when there is no digit before the decimal point
and all digits after the decimal point is 0, causing big.Int SetString
to fail because there is no string to parse.

Fix #134.

cd690d0c9e Make NewFromFloat respect the precision of the input (#100)
* Make NewFromFloat respect the precision of the input

Restores the previous behaviour where input converted from float is truncated at the precision of the float.

The precision is depending on the actual value. Simply making it 15 digits would make it faster, but would in some cases lose some precision. So the code from the stdlib that does this calculation (very well) has been included.

Lots of good articles here: https://www.exploringbinary.com/decimal-precision-of-binary-floating-point-numbers/

Performance is around the same as the previous string roundtrip since it basically does the same, but allocations are a bit less.

`BenchmarkNewFromStringFloat` is the old method, `BenchmarkNewFromFloat` is the new.

```
BenchmarkNewFromFloatWithExponent-8     10000000               260 ns/op             174 B/op          4 allocs/op
BenchmarkNewFromFloat-8                  2000000               744 ns/op              90 B/op          2 allocs/op
BenchmarkNewFromStringFloat-8            2000000               822 ns/op             258 B/op          6 allocs/op
```

* Update Sin/Tan/Cos tests.
