TableMath
Performs mathematical operations on a table of real (floatingpoint) numbers. This function supports minimum, maximum, average, standard deviation, and total operations on a table of values. Use this function for operating on tables returned from the trend system with the TrnGetTable() function. You can set the Mode to either accept or ignore invalid or gated data returned from TrnGetTable().
Notes:
This function cannot check the length of any arrays passed to it.
If the array is shorter than the size argument, unpredictable
results can occur, such as data in memory being overwritten, or a
general protection fault.
This function only supports arrays declared in Cicode and not
variable tag arrays.

UNINTENDED EQUIPMENT OPERATION Always confirm that arrays are of appropriate length before passing them to the TableMath function. Failure to follow these instructions can result in death, serious injury, or equipment damage. 
Syntax
TableMath(Table, Size, Command [, Mode] )
Table:
Any table of floatingpoint numbers.
Size:
The maximum number of items in the table.
Command:
The mathematical operation to perform on the table:
0  Minimum
1  Maximum
2  Average
3  Standard deviation
4  Total
Mode:
The mode of the operation:
0  Operate on all data  default
1  Ignore invalid or gated data returned from the TrnGetTable() function
Return Value
Returns the value related to the requested mathematical operation performed on the table (Minimum, Maximum, Average, Standard deviation or Total).\

Example
REAL Array[5]=10,15,50,100,200;
REAL Min,Avg;
! Get the minimum value.
Min=TableMath(Array, 5, 0, 0); ! Sets Min to 10.
! Get the average value.
Avg=TableMath(Array, 5, 2, 0); ! Sets Avg to 75.
