How can you make python round numbers to the nearest 5:
Example:
3 => 0
8 => 10
23.2 => 20
36 => 35
51.5 => 50
I'm not sure *any* rounding system will give those results. 3
should round up to 5 (not down to 0) and 23.2 should round up to
25 (not down to 20) in the same way that 8 rounds up to 10.
tests = (
(3, 5), # not 0
(8, 10),
(23.2, 25), # not 20
(36, 35),
(51.5, 50),
)
for x, expected in tests:
result = int(round(x / 5.0) * 5)
if result != expected:
print "Failed:", x, result, expected
break
else:
print "All tests passed"
