## Round function

 The round function in Octave rounds to the nearest integer while round in MATLAB supports rounding to arbitrary precision: round(x,n) rounds x to n decimal places. This is just a suggestion/request that it would be handy for the Octave function to work like the equivalent MATLAB function. This capability can be important when needing to compare numbers using == when  numerical noise can cause problems. Sent from my iPhone

## Re: Round function

 This is actually an easy fix, new_round = @(x, n=0) round (x * 10^n) * 10^(-n) If you could send a patch to the patch tracker with: 1. extended documentation 2. new code 3. a few test cases I would be happy to apply the patch and push it.

Depending on what you expect it to do. Regards, Allen
