Hey guys. I’m new to no/low code apps so feel free to explain it like I’m a 5 year old. I’m creating a calculator from an excel model and there’s a hand-full of excel expressions that I’ve had to “work around” in my math. Ultimately the output comes down to an exponential function that will requi…

You can do LOG and exponents in a Math column. What is the formula you are trying to reproduce? And do you have an example of values you are feeding the formula and the expected result?

Thanks for the quick reply, Jeff. Unfortunately LOG and LN (natural log) are NOT the same thing. [image] Difference Between Log and Ln (Logarithm v/s Natural Log) The basic difference between log and ln is that log is represented with base 10 and ln is denoted by base e, where e is the…

Something like this in a javascript column? I’m not sure if that’s exactly what you’re looking for. That’s why I asked for a current sample formula that you are using in excel and a sample result. [image] function naturalDecay(initialQuantity, decayConstant, time) { return initialQuantity *…

Thank you Dilon. I messed around with this some. It appears to only work on a single value? Is there a way to perform the calcs for an entire column? I have an entire column of data that I need to take the “natural log” of. Data (input) LN (Data) 350 LN(350) …

Thank you, Jeff. Here’s a bit more clarity. Produce is an Input from the user. Each row will have to be calculated like the excel screencap. I was able to use the “Excel Formula” option but I was only able to perform the task on a single value. I’m new to this, would using a java script be bett…

Not sure why it’s “only able to perform the task on a single value”? If you add a column like Jeff or Dilon showed, wouldn’t it apply to every row? Can you add a screenshot?

Perfect Timing! I just figured it out. I wasn’t referencing the column properly. Thank you
