The isub is a built-in function that returns the difference all of its
arguments starting from the leftmost arguments and returns the result as an Integer
quantity. The operands are not checked and are not coerced.
When to use Use the isub to compute the difference of an arbitrary number of Integer
operands. The isub built-in function is a simple but very fast integer
subtraction function. Use the isub function for highly optimized integer
subtraction. An alternate function, subi, will take any numeric operand and
will perform type conversion before subtracting and returns an integer result,
but is much slower.
(isub int1 int2, ... ) The difference all of its arguments starting from the leftmost arguments
expressed as an Integer quantity
Here are a number of links to Lambda coding examples which contain this instruction in various use cases.
These examples show the isub function perform subtraction on the Integer arguments
The function does not operate on non-Integer arguments.
Here are the links to the data types of the function arguments. Here are also a number of links to functions having arguments with any of these data types.
