Based on http://www.mredkj.com/javascript/nfbasic2.html, following code will result in 5.6e+2.

num = 555.55;

result = num.toPrecision(2); // result will equal 5.6e+2

How can I let the output of the result variable be displayed without scientific notation (i.e., e)?

To get a float with reduced precision, you could use toPrecision() like you do, and then parse the scientific notation with parseFloat(), like so:

result = parseFloat(num.toPrecision(2));

If you do not wish to reduce precision, you could use toFixed() to get the number with a certain number of decimals.
