Is it even possible to use AppleScript to perform this calculation?

Thanks for any help you might offer.
on WindChill(T, V)
set F to 35.74 + (0.6215 * T) - (35.74 * (V ^ 0.16)) + ((0.4275 * T) *
(V ^ 0.16))
set F to round F
return F
end WindChill
set F to WindChill(40, 5)
--> 36
set F to WindChill(-15, 25)
--> -44
