A 4. 16 Add

Computes the sum of the inputs. If you wire two waveform
values or two dynamic data type values to this function, error in and error
out terminals appear on the function. You cannot add two time stamp
values together. The dimensions of two matrices that you want to add must
be the same. Otherwise, this function returns an empty matrix. The
connector pane displays the default data types for this polymorphic
function.

A 4. 17 Number To Decimal String

wider if necessary. If number is floating-point or fixed-point, it is rounded to a
64 - bit integer before conversion.

A 4. 18 Decimal String To Number

Converts the numeric characters in string, starting at offset, to a decimal integer

and returns it in number.
