## Floating point arithmetic, again [Software]

Hi Ohlbe,

[1] FALSE

We (as in us humans) should just switch to binary and we'd never have these discussions. We can still keep the metric system but to keep things easy we may wish to define a millimeter as 1/1024 of a meter, if we wish to impress someone by our ability to do division and multiplication in our heads

In a nutshell, try:
 a=.11111111111111111111111111111111111111111111111111111111 b=.111111111111111111111111111111111111111111111111111111111 (a-b)==0
