Math functions perform basic arithmetical operations on input data obtained from various data sources.

 

All supported math functions are listed below:

const-function, min-function, max-function, sum-function, subtract-function, average-function, multiply-function, divide-function,

ceil-function, divide-function.

Attributes:

id - unique identifier of this resource in the current processing job.

 

Children elements:

 

<das:in-param> - specifies the source of the operands. Irrelevant for const-function. Ceil-function, floor-function, modulus-function support

just one input parameter. If more than one parameter is specified, only the first one will be considered and the rest will be ignored. Min-function, max-function, sum-function, subtract-function, average-function, multiply-function support any number of input parameters. Divide-function supports only two named parameters divisor and divident.

 

<das:return-value> - specifies the id from which the result value of the function will be referenced in the current job.
