void QgsMathUtils::doubleToRational	(	double	value,
		qlonglong &	numerator,
		qlonglong &	denominator,
		double	tolerance = 1.0e-9,
		int	maxIterations = 100 )

static

Converts a double value to a rational fraction.

Parameters

value	value to convert
numerator	calculated numerator
denominator	calculated denominator
tolerance	desired precision. The returned fraction will be at within this tolerance of the original value.
maxIterations	maximum number of iterations. Higher values result in better approximations, but at the cost of additional computation.
