translating javasript formula to perl code

[webscripter]

Hi everyone,

I have a wind chill formula that uses exponential notation, which I'm new to. Can someone tell me how to write t his equation in perl.

windchill=(13.12+0.6215*temp-11.37*Math.pow(wind,0.16)+0.3965*temp*Math.pow(wind,0.16));



Thanks

Your formula looks something like this:

$windchill = 13.12 + (0.6215 * $temp) - (11.37 * ($wind ** 0.16)) + (0.3965 * $temp * ($wind ** 0.16));

However, I must be missing something. I looked around a bit and NOAA/NWS has a different formula for calculating wind chill that looks something like this:

$windchill = 35.74 + (0.6215 * $temp) - (35.75 * ($wind ** 0.16)) + (0.4275 * $temp * ($wind ** 0.16));
