JASS has no ^ operator
i think you mean Pow(a,p)
also most languages that do have an ^ operator it implements exclusive OR rather than exponentiation..

also..
does it have SquareRoot function? i would guess not ..
pow(a,0.5) is so trivial i dont see a reason for a separate square root function..

JNGP has a nice function library where u can look at all the built in functions, i would suggest to use it.

Because square root on floats is way cheaper than that.

@Coke, good point. totally missed that

Can anyone clarify what I am doing wrong?

function GetPitch takes real speed, real gravity, real horizontal_distance, real vertical_distance returns real
    local real pitch = Atan((Pow(speed, 2) + SquareRoot(Pow(speed, 4) - gravity *(gravity * Pow(horizontal_distance, 2) + 2 * vertical_distance * Pow(speed, 2)))) / gravity)
    call BJDebugMsg("Pitch = " + R2S(pitch))
    return pitch
endfunction



function Trig_Test_Actions takes nothing returns nothing
    
    call GetPitch(50, 9.81, 100, 10)
    call GetPitch(100, 9.81, 100, -10)
    call GetPitch(50, 9.81, 300, -150)
    call GetPitch(400, 9.81, 300, 100)
    call GetPitch(100, 9.81, 1000, 10)
    call GetPitch(50, 9.81, 1000, 10)
    
endfunction

Response:
Pitch = 1.569
Pitch = 1.570
Pitch = 1.569
Pitch = 1.571
Pitch = 1.570
Pitch = 1.567

Can't be right.
