I'm not completely sure whether I'm allowed to post this (I'd guess so though), but EnEsCe recently gave me a modified 2.6.1 binary and .exe that includes some more basic mathematic functions that i needed for my hexer script. The new functions are:
function tan(x: real): real
calculates tangent of angle x (rad)
function arctan(x: real): real
calculates arcustangent of angle x (rad)
(sin() and cos() were there before, no tangent or arcustangent though)
function LogN(n,x: real): real
calculates "result": x^result = n
I think some other stuff was added aswell.
As soon as i get the permission of EnEsCe (and hopefully a completition of the list above), i'll upload the improved binary and .exe
