5. To obtain a temperature in Celsius, divide the previous result by 2. For Fahrenheit, multiply
the Celsius value by 9, divide by 5, and add 32 (F = 9/5 C + 32).

Please note that the least significant temperature DATA-byte is in terms of a 0.5 ° C. The sign bit
is duplicated into all of the bits of the most significant DATA-byte.
The second format provided by this device for temperature is in IEEE 754 Floating-Point
Standard (single precision) and has a useable resolution of 0.1 degree Celsius. Commands that
query register or variable
<02h> in the Sensorsoft Thermometer will receive a four byte response
in the DATA-byte(s) placeholder. Decoding these IEEE 754 Floating-Point bytes is beyond the
scope of this document.
