say sprintf('%f %f %f %f', Mu, Any, Nil, NaN); # output​: rakudo-moar ed47bb​: OUTPUT«0.000000 0.000000 0.000000 0.000000␤» # rakudo-jvm ed47bb​: OUTPUT«java.lang.NumberFormatException​: For input string​: "nan"␤» # NaN should numify to NaN for sure and so may Mu, Any and Nil

The output for NaN is NaN now, the rest is unchanged​:

$ perl6-m -e 'say sprintf("%f %f %f %f", Mu, Any, Nil, NaN);' 0.000000 0.000000 0.000000 NaN

My idea is to not allow Mu as a value to sprintf: each value should be Cool in the RakuAST implementation of sprintf in 6.e.

This would mean that a Mu would cause a typecheck error.
