static doubleToRational(value: float, tolerance: float = 1e-09, maxIterations: int = 100)[source]¶

Converts a double value to a rational fraction.

Parameters:

value (float) – value to convert
tolerance (float = 1e-09) – desired precision. The returned fraction will be at within this tolerance of the original value.
maxIterations (int = 100) -> (int) – maximum number of iterations. Higher values result in better approximations, but at the cost of additional computation.

Returns:
