The way the scientific and engineering communities predominately write real numbers is by using SI scale factors.
I don't believe it, not with naked scale factors as you have proposed. I have worked in science and I never saw naked scale factors until this proposal. The scale factors are usually attached to units.
These numbers almost always represent physical quantities, so it is common to write the number with scale factor and units.
The scale factor is part of the unit, and people now learn this in grade school, I presume.
So for example, the distance to Andromeda is 780kpc, the pressure at the bottom of the Mariana Trench is 108MPa, the total power produced by a typical hurricane is 600TW, the number of base pairs in human DNA is 3.2Gb, and the Bohr radius is 53pm.
These are all scaled units and to me not relevant to the proposed addition of scale factors without units.
At this point I quit reading. -- Terry Jan Reedy _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
