Range limitation on ln(x) in FPGA

Hi,

I am studying Labview FPGA and trying to understand some underlying concepts.

Can anyone tell me why is there a range limitation of 1/e < x < 1 for ln(x) in labview fpga?

I am guessing it has something to do with resource usage.

Can anyone explain to me what is the advantage of working with this range?

Did you read the help for that specific function?

The "Why?" is answered by "the CORDIC algorithm this function uses".

And there is a "Details" paragraph giving you an algorithm to solve the ln(x) for values outside the range [1/e, 1]…

Best regards,
