The Negation/Minus Function -

Monadic Use On Floats And Integers

- is a monadic function that returns the negation of the argument.

- 1 3 5

¯1 ¯3 ¯5

- ¯2 4 ¯6

2 ¯4 6

Dyadic Use On Floats And Integers

- is a dyadic function that works in two ways.

If the rho of both sides is the same it performs zip-wise subtraction

If either side has a rho of [1] it subtracts the value from every value in the other.

Here are some examples:

1 2 - 3 4

¯2 ¯2

and

 1 2 3 4 5 - 33

¯32 ¯31 ¯30 ¯29 ¯28

and

1 - 22 33 44 55

¯21 ¯32 ¯43 ¯54

Monadic Use On Complex Nos

The minus function performs normal sign reversal on both parts of a complex no:

- 3J¯5

¯3J5

Dyadic Use On Complex Nos

This is normal complex subtraction - both parts are subtracted:

1J2 3J¯3 - 4j¯5 ¯1j4

¯3J7 4J¯7

Dyadic Mixed Use On Complex Nos And Real Numbers

In mixed use the real numbers are cast to a complex number with an imaginary value of zero:

1 3J4 - 3J4 1

¯2J¯4 2J4
