[issue41528] Use math module in turtle

[Terry J. Reedy]

Terry J. Reedy  added the comment:

You could post a suggested replacement for a couple of the expressions, with 
the warning that we would not necessarily use it.  math.hypot has recently be 
worked over so that it is perhaps more accurate than the  standard C version.

Complex numbers to be considered, of course.
My first pull request, so I'd rather not make such a revolution this time. :)

[issue41528] Use math module in turtle

[Vedran Čačić]

Vedran Čačić  added the comment:

Well, if you want to exploit Python features in full, I'd suggest cmath as even 
better library. Turtle position is just a complex numbers, and cmath has direct 
conversion from and to polar coordinates, which is all that's needed for basic 
commands. :-)

[issue41528] Use math module in turtle

[Marek Madejski]

New submission from Marek Madejski :

"Turtle" module is closely related to geometry, which is also covered by "math" 
(and "cmath") module. Nevertheless, in many places in "turtle" the wheel is 
being reinvented. Currently, only π and basing trig functions are used.
Performance may be improved by such refactor (for example, by using 
"math.hypot" instead of manual calculation of vector norm).
