There are a few places in Axiom where an expression needs to be
linearised: this is one of them and printing parameterised types is
another. Somebody had the bright idea of using the facility for
conversion to Fortran (which I wrote) which by default uses the double
precision names for intrinsic functions, with the results you see. I
remember reporting this as a bug when Axiom was still an IBM project,
before it even came to NAG!
