Pi is a geometric constant, so obviously we're redefining the decimal numbering system to make "1" anchored to a fixed value of π/5 (or simply 1 in our superior new decimal representation).

Don't believe the haters who'll complain about "needing integer number representations". Literally anyone with a basic grasp of fractions will be perfectly fine! Let's illustrate with a few simple examples:

• "I'll take three-fifths pi gallons of blue slushie, please"
• "No thanks, I don't need any cups because I actually brought two-fifths pi containers of my own each with three-tenths pi gallons of individual capacity specifically for this purpose".

As you can see, there is no reason to be concerned whatsoever. The system works. It is mathematically elegant.
