I am trying to use ATan2 in Tier 1 Build 107 but it is not recognised by the compiler. Is this a later command or do you know what is wrong?

Sincerely,

Doesn't appear to work in v107 but does work in v108b12. Could be something that has been added in v108 but I can't find any evidence of it in the change log.

I created my own atan2 function.

+ Code Snippet

function Myatan2(y as float, x as float)
    pi# = asin(1) * 2
    if x <> 0
        arctan# = atan(y/x)
    endif
    if x > 0
        returnvalue = arctan#
    elseif y>=0 and x<0
        returnvalue = pi# + arctan#
    elseif y<0 and x<0
        returnvalue = arctan# - pi#
    elseif y>0 and x=0
        returnvalue = pi# / 2
    elseif y<0 and x=0
        returnvalue = pi# / -2
    endif
endfunction returnvalue
