1== 1 is False?

[Curly Joe]

Not sure what you mean by more exactness, and why
rounding wouldn't work as in 
x = 2.260212
y = 2.260212
print "%f and %f are " % (x, y),
##---  round to 3 digits
if round(x, 3) == round(y, 3) :
    print "Equal to 3 decimals"
else :
    print "Not Equal"

x += 0.000001
print "%f and %f are " % (x, y),
if round(x, 3) == round(y, 3) :
    print "Equal to 3 decimals"
else :
    print "Not Equal"

This prints:
2.260212 and 2.260212 are Equal to 3 decimals
2.260213 and 2.260212 are Equal to 3 decimals

This is one of the things that we have to learn to
live with in a binary number system as far a I know,
just like we have to truncate/round numbers like 10/3
or 10/6 in our base 10 system.
