MATLAB: How to concatenate the rounded digits of a number and a string

Question

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***

Answer 1

xstar=sprintf('%.2f%s',round(x,3,'significant'),star)
