我正在尝试确定公制风寒度。我找到了一些 good information from the BBC (它被称为“感觉像温度”)，但我不太清楚如何将它转换为 C 代码。
这是他们的计算信息:
T(wc) = 13.12 + 0.6215T - 11.37V**0.16 + 0.3965TV**0.16
有了这些笔记
(Where T(wc) is the wind chill index based on the Celsius scale, T is the air temperature in °C, and V is the air speed in km/h measured at 10 m (33 ft, standard anemometer height).
所以我创建了这个，但我得到的输出有时是负的
float feelslike = 13.12 + 0.6215 * temperature - 11.37 * windSpeed * 0.16 + 0.3965 * temperature * windSpeed * 0.16;
也许我遗漏了什么？我假设当它有“0.6215T”时，它的意思是“0.6215 * T”，但我也不确定如何解释等式中的双“*”。

最佳答案
T(wc) = 13.12 + 0.6215T - 11.37V**0.16 + 0.3965TV**0.16
意思是:
T(wc) = 13.12 + 0.6215*T - 11.37*pow(V,0.16) + 0.3965*T*pow(V,0.16)
