Warning: </b><dd>
This function is known not to work for most precisions: it performs a fixed number of Newton-Raphson iterations (two), starting with a FP number (53 bits), so provides roughly 210 bits of precision. It should be modified to perform more iterations if more precision is needed. </dl>
