Exponentiation with infix operators in (or operating on) the base: Difference between revisions

=={{header|Smalltalk}}==

Smalltalk has no prefix operator for negation. To negate, you have to send the number a "negated" message, which has higher precedence than any binary message. Literal constants may have a sign (which is not an operation, but part of the constant).

b := 3.

Using the "negated" message:

Transcript show:'5 negated**3 => '; showCR: 5 negated**3.

Transcript show:'5**2 negated => '; showCR: 5**2 negated. "negates 2"

Transcript show:'(-5**b) negated => '; showCR: (-5**b) negated.

Transcript show:'-5 negated**2 => '; showCR: -5 negated**2. "negates the negative 5"
