how do I print number to 1dp - or 0 dp if an integer?

Hi, I guess the title says it all.

I'm using

MATLAB code
sprintf('%.0f', testval) %to print to 0 dp
sprintf('%.1f', testval) %to print to 1 dp

Is there a way to (simply) print to 0dp if testval is an integer, but 1dp if it has any decimal part?

Thanks a lot,

Tom.

You can use rem()

   rem(1.5,1) % gives 0.5

while

   rem(3,1) % gives 0

    testval = 3.5;
    if (rem(testval,1)~=0)
      disp('testval has a decimal part');
    else
      disp('testval is an integer');
   end
