Arith Sumn

Schema

This block is more or less obsoleted by the "Arith [ Sum+ ] " block, which allows for an arbitrary number of input pins. The "Sumn" block will remain in the library, but new actions should use "Sum+" (as it looks better in a diagram).

Trigger

At least the first 2 inputs must be connected and both must have received a value for the action to trigger ("and" input behavior). If present, additional values from other pins are added to form the sum. If no value is present, or the pin is unconnected, a 0 (zero) is taken as operand.

Operation

This block returns the sum of all given numbers, i.e.

sum = number1 + number2 + ... + number10

Automatic Type Conversion

The block allows for mixed mode arithmetic. This means that all combinations of Float, Double, Integer, LargeInteger, Fractional and FixedPoint Decimal numbers are allowed as input.

Depending on the input type(s), the output number is generated as:

in1	in2		out
Integer	Integer		Integer (1)
Integer	Float / Double		Float / Double
Integer	Fraction		Fraction (2)
Fraction	Fraction		Fraction (2)
Fraction	Float / Double		Float / Double
Float / Double	Float / Double		Float / Double

Notes:
(1) Integers are not limited to a 32bit range. If the result does not fit into a smallInteger, a largeInteger representation with an arbitrary number of digits is automatically chosen (32, 64, 96, 128... bits).

(2) If the fraction can be reduced to an integral value, an Integer is returned (i.e. 6/3 will be reduced to 2)

(3) If the imaginary part of the result is zero, a real result (one of Integer, Float,...) is generated

Revisions

This block has been in the Standard Library since 0.1.
