A.6.10 Other Functions

AddPrecise

UsedinconjunctionwithMovePrecise,allowshigh‐precisiontotalizingof

variablesormanipulationofhigh‐precisionvariables.

Syntax

AddPrecise(PrecisionVariable, X)

AvgRun

Storesarunningaverageofameasurement.

Syntax

AvgRun(Dest, Reps, Source, Number)

Note AvgRun() should not be inserted within a For / Next construct with the

Source and Dest parameters indexed and Reps set to 1. In essence this would be

performing a single running average, using the values of the different elements of

the array, instead of performing an independent running average on each element
