Change name for →Qπ - please suggest!

[Han]

RATCOMP

Rational Composition -- all the results are essentially the composition of ->Q(X) with one of the following functions: 1(X) (identity), SQRT(X), EXP(X), LN(X), or PI(X) (multiplication by PI).

For a shorter name:

QFORM

Q for rational, and FORM because the program converts the numerical value into some form involving a rational value. Or perhaps RATFORM

If not QPI, then I would lean in favor of RATCOMP
