The PID Editor contains a resonably power equation editor that allows you to manipulate the incoming data from an OBD device, Sensor, or other data input to the app

== Functions ==

The equation editor supports the following functions

* RANDOM()  Returns a random number between 0 and 1

* TAVG(seconds, value)  Timed average.  This averages the incoming data for the configured amount of time (in seconds). Data older than the configured time is removed from being averaged

* RAVG(value) Rolling average. This averages incoming values until it is reset.

* AVG(bucketSize, value)  Point average. This averages incoming values into a bucket.  The bucket can be configured to average a set amount of values, so AVG(10,value) would average the last 10 values

* SIN(value), COS(value) ,TAN(value).  Trigonometric functions are supported

* LOG(value) Returns the natural logarithm (base e) of a value

* LOG10(value) Returns the base 10 logarithm of a value

* LOG1P(value) Returns the natural logarithm of the sum of the value and 1

* INT(value) Converts the incoming number to an integer

* SQRT(value) Returns the correctly rounded positive square root of a value.

* ABS(value). Returns the absolute value of the number given 

* SIGNED(value) Treats the incoming value as 8bit signed

* BARO() Returns the barometric pressure from the android device (if it supports it)
