Form Calculations off

[brad]

I have a form that calculates values from two fields and populates a third with the result. But the result is not correct?

Here is my expression

dmx-bind:value="inputAddTransactionGross.value.toNumber() - inputAddTransactionTaxes.value.toNumber()"

I suspect this is actually correct. You will need to round the number up.

It has to do with floating point precision – there are lots of articles for explanations out there but suffice to say, it’s not wrong…even though it really looks like it is.

So how would I round it off? Sometimes it needs to be rounded down …

[mebeingken]

The round formatter should take care of it for you, just specify the number of decimal digits you want.

Tried that.

dmx-bind:value="(inputAddTransactionGross.value.toNumber().round(2)) - (inputAddTransactionTaxes.value.toNumber().round(2))"

There must be a way to add the round to the actual result that I am missing.

@brad

dmx-bind:value="(inputAddTransactionGross.value.toNumber().round(2)) - (inputAddTransactionTaxes.value.toNumber().round(2))"

You need to round the result, not the values you get from the inputs.

dmx-bind:value="(inputAddTransactionGross.value.toNumber() - inputAddTransactionTaxes.value.toNumber()).round(2)"

Thanks Patrick, you are a God!
