Hi,
I have an array with multiple floating value's. I would like to round them to the nearest two digit number. I used
round(x,2)
This rounds 1.32456778 to 1.3200000. But I would like the result 1.32 (without the zeros). Because I want to display the value in a graph as text, and now it displays 1.320000E+00
qq = 24;
qw = 41.2;
y = sprintf('Vote = %d', round(x,2) );
qe = text(qq,qw,y, 'FontWeight', 'bold', 'FontSize', 8);
Can someone help me?

Use %f as a format holder rather than %d, and specify the number of decimals, like this
x = 1.320001
sprintf('%.2f',x)
