Round function

[Rory Conolly]

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.

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.

new_round(pi, 1.5)

ans = 3.1307

Maybe new_round = @(x, n=0) round (x * 10^round(n)) * 10^(-round(n))?
Depending on what you expect it to do.
