How to concatenate the rounded digits of a number and a string?

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.

x=1.361620214248647;
star='***';
xstar=sprintf('%.2f%s',round(x,2),star)
