tuple_sub🔗
Short description🔗
tuple_sub — Subtract two tuples.
Signature🔗
tuple_sub( number D1, number D2, out number Diff )
Description🔗
tuple_sub computes the difference of the input tuples
D1 and D2. If both tuples have the same length
the corresponding elements of both tuples are subtracted.
Otherwise, either D1 or D2 must have length 1. In
this case, the subtraction is performed for each element of the
longer tuple with the single element of the other tuple. If two
integer numbers are subtracted, the result is again an integer
number. If one of the operands is a floating point number, the
result is a floating point number. The subtraction of strings is
not allowed.
Exception: Empty input tuples🔗
If either or both of the input tuples are empty, the operator returns an empty tuple.
HDevelop In-line Operation🔗
HDevelop provides an in-line operation for tuple_sub,
which can be used in an expression in the following syntax:
Diff := D1 - D2
