How to save a graph using print and rational numbers within image name without changing the file format?

MOTIVATION: The lines below display one example of how I'm trying to name a graph and save the image to the hard disk:

i=10.5;
f=figure;
x = 0:pi/100:2*pi;
y = sin(x-i);
h=plot(x,y);

title(sprintf('ATITLE%g',i));
print(f,'-dtiff', sprintf('ATITLE%g',i));

PROBLEM: When you run these lines, you will see that the file saved is not ATITLE10.5.tif but only ATITLE10.5 anything that I can't use.

QUESTION: I wonder if someone knows how to correct these lines so that the file saved is ATITLE10.5.tif?

I already tried the following approach suggested by Walter:

print(f,'-dtiff', genvarname(sprintf('ATITLE%g',i)));

But the result is ATITLE100x2E5.tif and does not help either.

I thank you in advance for your help Emerson

Our daily "how do I save a figure?" question. See the FAQ:

If you insist on "rolling your own" then try this:

baseFileName =  sprintf('ATITLE%g',i)
folder = pwd;
fullFileName = fullfile(folder, [baseFileName, '.tif'])
title(baseFileName);
print(f,'-dtiff', fullFileName);

Thank you,

this was the suggestion that I needed.

Wish you a nice day
