C++ (Cpp) clamp_precision Examples

Example #1

File: llspinctrl.cpp Project: mmorciegov/emeraldviewer

void LLSpinCtrl::updateEditor()
{
	LLLocale locale(LLLocale::USER_LOCALE);

	// Don't display very small negative values as -0.000
	F32 displayed_value = clamp_precision((F32)getValue().asReal(), mPrecision);

//	if( S32( displayed_value * pow( 10, mPrecision ) ) == 0 )
//	{
//		displayed_value = 0.f;
//	}

	std::string format = llformat("%%.%df", mPrecision);
	std::string text = llformat(format.c_str(), displayed_value);
	mEditor->setText( text );
}

Example #2
