+## Temperature
+The GVH5074 uses [Two's Complement](https://en.wikipedia.org/wiki/Two%27s_complement#Converting_to_two's_complement_representation) for negative numbers.
+> In two's complement notation, a non-negative number is represented by its ordinary binary representation; in this case, the most significant bit is 0. Though, the range of numbers represented is not the same as with unsigned binary numbers. For example, an 8-bit unsigned number can represent the values 0 to 255 (11111111). However a two's complement 8-bit number can only represent positive integers from 0 to 127 (01111111), because the rest of the bit combinations with the most significant bit as '1' represent the negative integers −1 to −128.
+> 
+> The two's complement operation is the additive inverse operation, so negative numbers are represented by the two's complement of the absolute value.
+
+The berry language has a `geti` [method](https://github.com/berry-lang/berry/wiki/Chapter-7#get-geti-methods) that will return a signed value.
+
+> Read a 1/2/4 bytes value from any offset in the bytes array. The standard mode is little endian, if you specify a negative size it enables big endian. `get` returns unsigned values, while `geti` returns signed values.
+> `b.geti(<offset>, <size>) -> bytes object`
+
+In order to get the temperature in °C, use the `geti` method and then divide by 100.0
+```
+# Example
+adv_data = bytes('88EC0052FA6E166402')
+temp = adv_data.geti(3,2) / 100.0
+```
+Output 
+```
+-14.54
