fn algorithm_r<T: RawFloat>(f: &Big, e: i16, z0: T) -> T

Unstable (dec2flt)

: internal routines only exposed for testing

An iterative algorithm that improves a floating point approximation of f * 10^e.

Each iteration gets one unit in the last place closer, which of course takes terribly long to converge if z0 is even mildly off. Luckily, when used as fallback for Bellerophon, the starting approximation is off by at most one ULP.
