That's a myth. Decimal suffers from the same floating point issues as
binary floats. It's quite easy to demonstrate the same sort

Unfortunately they don't work together.
range(0.1,0.5,0.1) -> [0.1,0.2,0.3,0.4] doesn't work
you need to do:
for n in range(1,5): use( n/10 )
There ar

Hi:
I have bunch of coordinates for various vectors.
example:
small vecs:
name cord. Xcord. Y Sector no.
smvec175 1001aa
smvec225 50 1aa
smvec3135 1551ab
