Check out my code snippet:
Math.floor((7/2)*100)/100
The expected output is "3.50", however, it currently outputs "4.00". Can you help me figure out how to round this value without rounding up?
Check out my code snippet:

The expected output is "3.50", however, it currently outputs "4.00". Can you help me figure out how to round this value without rounding up?
The output should be "4.00". This is because the number 3.5 was rounded to 4 before applying the toFixed(2) method.
If you want the output to be "3.50", avoid rounding the number to a whole number first. The toFixed method will round to the specified number of decimal places without needing prior rounding:
(7/2).toFixed(2)
For example:
snippet.log((7/2).toFixed(2));<!-- Script provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->
<script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script>Here's an example where toFixed does perform rounding:
snippet.log((1.237).toFixed(2)); // "1.24"<!-- Script provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->
