The documentation for normalDistribution and normalDistributionInverse does not state what mean and standard deviation are used. Presumably mean=0.0 and stdev=1.0; this is consistent with the cumulative distribution equation listed in the normalDistribution docs and the code for the z<1 case in std.internal.math.errorfunction.normalDistributionImpl. Still, it'd probably be a good idea for someone familiar with std.internal.math.errorfunction to double check that before updating the docs; there's some numerical stability code (I think) in there that I was unable to follow.
