Steps to reproduce the problem:
1. Round a variable to 4 decimals.
2. Multiply the variable by 100.
3. Output the results.

Example code:
<script>
var myVar = 0.07094330288549908;
myVar = Math.round(myVar * 10000) / 10000;
myVar = myVar * 100;
alert("This is not a rounded value: " + myVar);
</script>

What is the expected behavior?
The expected value of the variable myVar would be: 7.09

What went wrong?
The actual value of the variable myVar comes out as: 7.090000000000001
