I understand, but the functions do not return a value. The help file tells the obvious - to enter the angle in the sin()-function, but for instance neither sin(30) nor sin(pi/6) result in 0.5 but only ... is returned. The log-function works for all valid numbers, for instance log(100) = 2, except log(1) which should return 0 but results in ... (three dots).

FYI the error says (I have to translate to English):

Script error

After confirmation the plugin seems to work.
Nice.

Hi, Where do I find the download? Thanks, Daan.
