Description
ofToString() should always return as many digits of precision as are available from the floating point value. it looks like right now, at least 2 or 3 digits of precision are being ignored. this was not a problem with sprintf(), but is a problem with stringstream. this problem first became clear with issue #1516 and a temporary fix was made to ofxXmlSettings, but a deeper fix to ofToString() still needs to be made.

Research direction
Start at the implementation of ofToString() and compare its stringstream formatting with the sprintf() behavior described in the issue. Inspect the temporary fix in ofxXmlSettings and issue #1516 for context; done means ofToString() preserves all precision available from the floating-point value without relying on that workaround.
