BS2sx Natural Log function???

Sarah Rose

I know that the RCTIME function uses ln() in its calculations,

but is it possible to have it compute a natural log in your code?

As in, could you write a code and make one variable the natural log of 2 others?

Ex: 3 = ln(1/2)

Thanks,
Sarah

Hm..can it even do exponential functions? I think I'm realizing it cannot...

Hi Sarah,

The Stamp does have integer base 2 log and exp functions, but they are called ncd and dcd and their function as log and exp is not immediately apparent. There is an explanation of how it works and also how to compute the functions with greater accuracy at this URL:

Also, for an application that uses the logs to calculate dew point temperature, see

-- the dew point stuff is near the bottom of the page.
