I have scoured the internet and I haven't found a solution that really works for me, yet.
var tv = Length * Type;
if (tv < 0)
{
cForm.voltage.value = "-" + Math.abs(tv) + " V";
}
else...
Some of the calculations with these two numbers come out to about the 15th decimal for some reason. I would like to limit the decimal amount that is returned, and NOT allow the number to round up or down. On a calculator it only comes out to about the third decimal, but Math.abs() brings it too far out.
.toFixed() Doesn't work for me because if the number only has 2 decimals it will add additional zeros at the end. I only want to display up to the fourth if it is calculated.
Just expanding on @goto-0 s comment, with the correct # of decimal places.
var tv = Length * Type;
if (tv < 0)
{
cForm.voltage.value = "-" + (Math.round(Math.abs(tv) * 10000) / 10000) + " V";
}
else...
