How to Calculate on a Ubuntu Server
hi guys. is there a way to calculate numbers and get the accurate results as oppose to the results one gets from using the expr command.

i want to be able to calculate numbers like 1/3 and get the exact results. any help on this is much appreciated. thanks guys

with expr, 1 diveded by 3 = 0

i want something that gives the .33333

thanks jim. this code gives a 0.000000. that isn't accurate. is there a way to get the same output one would get from using a calculator?

Yes, it does. Only not in an interactive shell, since bashs read doesn't work there. Use it in a script.
