VBOX Video HD2 Maths Channels Functions

Maths channels can be utilised by the VBOX Video HD2 to display information from a combination of existing parameters. An example may be hill gradient which can be calculated from the horizontal speed and the vertical speed.

Maths channels can be configured using the VBOX Video HD2 Setup Software for Windows.
 

Supported functions are shown below. Constants of G and PI are also supported.

+ Add - Subtract
* Multiply / Divide
% Remainder << Bitwise left shift, the most-significant bit is lost, and a 0 bit is inserted on the other end, multiplies a binary number by 2
>> Bitwise right shift, the least-significant bit is lost, and a 0 bit is inserted on the other end, divides positive numbers by 2 & Bitwise AND, whenever the value of a bit in both the variables is 1, then the result will be 1 or else 0
| Bitwise OR, whenever the value of a bit in one of the variables is 1, then the result will be 1 or else 0 ^ Bitwise XOR, whenever only one variable holds the value 1, then the result is 0 else 0 will be the result
!= Non-equality, checks whether unequal, returns 1 for true or 0 for false <= Less than or equal, returns 1 for true or 0 for false
>= Greater than or equal, returns 1 for true or 0 for false < Less than, returns 1 for true or 0 for false
> Greater than, returns 1 for true or 0 for false Abs(x) Absolute
Acos(x) Arc cosine, returns radians Asin(x) Arc sine, returns radians
Atan(x) Arc tangent, returns radians Ceiling(x) Round up to the nearest integer
Cos(x) cosine, returns radians Cosh(x) hyperbolic cosine, returns radians
Deg(x) Convert radians to degrees Exp(x) Exponential function
Floor(x) Round down  Heavyside(x) Returns 0 if x less than 0, otherwise returns 1
Integer(x) Integer part of x Ln(x) Natural log of x
Log10(x) Logarithm to the base 10 Max(x,y) Maximum of x and y
Min(x,y) Minimum of x and y Modf(x) Fraction part of x
Pow(x,y) Raise x to the power of y Rad(x) Convert degrees to radians
Round(x,y) Round the number x to y decimal places Sin(x) Sine, returns radians
Sinh(x) hyperbolic sine, returns radians Sqrt(x) Square root
Tan(x) Tangent, returns radians Tanh(x) hyperbolic tangent, returns radians
