It's posible to avoid ofxGui float/ofxSlider label style 2.8e-15 to 0.000028?

[moebiussurfing]

I was wondering if this is possible…
to improve the sliders visually and change 2.8e15 to 0.000028 or 0.000.
if there’s something like a setPrecision(3) could do the job

ofxGui float slider precision

Hello, I am using an ofxGui float slider that is updated with a float OSC received value. This value is normalized as a float betwenn 0 and 1. The slider displays a 6 decimal precision digit (ie : 0.234112) is there a way to limit the float precision to only 2 decimal for exemple ? thank you

You can add following lines in ofxSlider.h and ofxSlider.cpp

// ofxSlider.h
// somewhere in the public section
int precision = 0;
void setPrecision(int p){precision = p;};

// ofxSlider.cpp
// around line 230 
void ofxSlider<Type>::generateText(){
	//string valStr = toString(value.get());   // original code
	string valStr = ofToString(value.get(), precision);
	...

And then use it like following.

// ofApp.h
ofxFloatSlider mySlider;

// ofApp.cpp
mySlider.setPrecision(4);

I did a quick test and it is working.
But it might cause an unexpected side effect because of a template.
