Change name for →Qπ - please suggest!

I think we (myself included) are overthinking the naming of this feature. We set the entry mode to "Textbook" for a 2D display, we set "Textbook" in Home settings for the history display. Couldn't it follow to also set the representation of the floating point (numeric) output to "Textbook" as well?

I can imagine a student wanting the floating point number to match the nice result in the textbook. So...

Would calling TEXTBOOK() on a floating point be too abstract an idea? If it isn't, the name could allow for future expansion of the capabilities without becoming misunderstood.

(I also like the simplicity of EXACT() )
