Hi everyone,
I am trying to concatenate a rounded number (in the 2nd digit after decimal) and string value, so that:
x= 1.361620214248647
star = '***'
xstar = sprintf('%d%s',round(x,3,'significant'), star)
I would expect the output to be 1.36***, rather than 1.360000e+00***

Why so complex? sprintf does rounding for you:
>> sprintf('%.2f%s',x,star)
ans =
1.36***

Hi there,
Thank you for answering my question. Nevertheless, the answer I get 1.360000***, but I would expect 1.36***, instead.
