95 Function
96
97 There are two modes to choose from (n):
98
99 Mode 0: Calculate the corresponding humidity by wet bulb temperature and dry bulb temperature.
100
101 Mode 1: Calculate the corresponding wet bulb temperature by dry bulb temperature and humidity.
102
103 The conversion process formula is as follows:
104
105 Assuming that the wet bulb temperature is A, the dry bulb temperature is B, and the corresponding current humidity is C, which meet the following conditions:

109
110
111 Precautions
112
113 ·The wet bulb temperature is not greater than the dry bulb temperature. When they are the same, the humidity reaches the maximum value 100%.
114
115 ·The unit of dry and wet bulb temperature is (^^o^^C).
116
117 ·The general value range of dry bulb is between 0~~100^^o^^C, and the command does not judge its range, so pay special attention when using this command.
