Rounding to two decimal places in Octave

Question

After a calculation I got 32.073 .I need it to round to 32.07 using Octave.Please can somebody help me?

You didn't specify if you need the rounded number or just printing it. The answer depends on this. — sancho.s ReinstateMonicaCellio, Aug 09 '20 at 22:51

You can do:

res = round(100 * 37.073) / 100

It gives 37.070. I need 37.07.Need to drop '3'. – AnoAPI Jul 11 '14 at 09:54
@AnoAPI you cannot. You either have a floating point like that or an integer (or you write your own class). See [Matlab/Octave addition, losing digits of precision](http://stackoverflow.com/questions/13886821/matlab-octave-addition-losing-digits-of-precision/13887079) – carandraug Jul 11 '14 at 12:09

you could use the C style printf format.

sprintf("%.2f", 32.073)

Not a great solution for matrices though. You would need a nested loop: https://stackoverflow.com/a/11386211/1271772 – Nike May 25 '23 at 04:48
