I am setting up a device that reads a thermistor and during my conversion of the thermistor resistance to temperature, I found what appears to be the math library excluded from the library. The conversion from resistance requires computing the natural logarithm of the resistance which becomes difficult without that library.
Now I haven't consulted my Calculus book, but from what I can recall, computing that by other means is not going to be pretty and possibly more than it's worth. The other issue is that on our server end, our vendor has seemingly left logarithms out as well.
So, does anyone out there have a clean way to performing the calculation of logarithms? I was thinking I could pull a library file from somewhere and load it, but I haven't come across anything.
My other solution was to create a table or parameterize a series of polynomials, but this gets a bit messy as well. One of my other half baked ideas, was to pump the raw data and have another machine (possibly in our office) perform the computations and then send it back to our cloud platform/dashboard (I am not too worried about latentcy).
