How can I write the following equation in C language?

Question

Old Wind Chill = 0.0817(3.71V0.5 + 5.81 – 0.25V)(T – 91.4) + 91.4

Thanks

Answer 1

Uh, how about any language. What does this mean:3.71V0.5?

Ok, I looked up the actual equation:

W = Wind Speed
T = Temp

Old Wind Chill = 0.0817(3.71 * sqrt(W) + 5.81 – 0.25W)(T – 91.4) + 91.4


In C, you basically just add * where you need to multiply:


#include
float getOldWindChill( float W, float T )
{
return 0.0817f*(3.71f*sqrt(W) + 5.81f – 0.25f*W)*(T – 91.4f) + 91.4f;
}

I put the f's on to avoid warnings about converting doubles to floats, but they really aren't necessary.
