What does "rounded" mean to you?

#

Why would 34 be converted to 30?

#

if you just want to round to the nearest 10, you can just use a ternary

# 
int rounded = (unrounded % 10 < 5)
  ? (unrounded - (unrounded % 10))
  : (unrounded + (10 - unrounded % 10))

That doesn't look simple to me, but I guess I wouldn't try to do much for someone who ignores the easiest and most obvious question

Math.round(number/10)*10

I think you misread something

34 rounded to the nearest ten is 30 I guess. based on what they said that code should work.

If I'm not wrong, 34*10 is 340 and rounding it make it stay 340

Here is your java(15.0.2) output @raw zenith

10
raw zenith

hmm

#

make sure it's a double

#

then it should work

real holly
#

how?

#

is that working?

#

in a double?

raw zenith
#

yes

#

multiply to a double

e.g. 10.0 10d or 10D
