	Integer part of the value.
int32_t	val2
	Fractional part of the value (in one-millionth parts).

Detailed Description

Representation of a sensor readout value.

The value is represented as having an integer and a fractional part, and can be obtained using the formula val1 + val2 * 10^(-6). Negative values also adhere to the above formula, but may need special attention. Here are some examples of the value representation:

 0.5: val1 =  0, val2 =  500000
-0.5: val1 =  0, val2 = -500000
-1.0: val1 = -1, val2 =  0
-1.5: val1 = -1, val2 = -500000
