inverseErf y
The inverse of erf.
i1 : erf 2 o1 = .995322265018953 o1 : RR (of precision 53)
i2 : inverseErf oo o2 = 2 o2 : RR (of precision 53)
This function always returns a double precision real number (53 bits) regardless of the precision of its arguments.
The object inverseErf is a method function.
