Precision

[bknecht]

My suggestion on how to fix issue #284. Sorry, it took so long. Stressful work and vacations delayed this.

StreamWriterBuilder has now a setting precision that can take values between 0 and 17. Default is always 17 as well as with deprecated classes where there is no option to limit precision.

Also added a small test to test different issues with precision and with changing the precision setting.

I hope this is solving the issue. Let me know if something is missing in your opinion.

We'll revert if somebody complains, but I can't imagine what could go wrong. Thanks!

Any idea if this is cherry-pickable to 0.y.z?

[bknecht]

The change does not use any C++11 features if that's what you mean. I don't know the 0.y.z branch, but if C++11 compatibility is the only issue, the change should be safe to cherry-pick.

[cdunn2001]

We don't have any automated tests on that branch. Could you cherry-pick and test it? Then submit a pull-request against that branch?

[bknecht]

I'll allocate some time this month to test this.

[KarateSnowMachine]

I'm planning on trying to cherry-pick this sometime in the next week or two; I'll let you know how it goes.

[KarateSnowMachine]

Welp, "next week or two" certainly didn't pan out, but I've finally cherry-picked this back to 0.x.y and submitted #408

Maybe the version of jsoncpp is inconsistent, mine is
JSONCPP_STRING valueToString(double value,
unsigned int precision,
PrecisionType precisionType) {
return valueToString(value, false, precision, precisionType);
}
I have no ideas.
