Arithmetic Operators

Elzed supports the following arithmetic operators:

addition

first + second

Returns the sum of two numeric operands.

division

first / second

Returns the quotient of the first numeric operand divided by the second.

exponentiation

first ** second
first ^ second

Returns the result of the first numeric operand raised to the power of the second.

factorial

number !

Returns the factorialization of a numeric operand. For example, 6! is equal to 6*5*4*3*2*1 = 720.

modulo division

first % second

Returns the remainder of the first numeric operand divided by the second. For example, 5 % 2 = 1.

multiplication

first * second

Returns the product of two numeric parameters. If implied multiplication is active, you may omit the "*", but be sure to leave a space between the operands.

post-decrement

variable--

Subtracts 1 from the named variable, but returns the variable's original value. For example, if variable fred is equal to 5, fred-- sets fred to 4, but returns 5.

post-increment

variable++

Adds 1 to the named variable, but returns the variable's original value. For example, if variable fred is equal to 21, fred++ sets fred to 22, but returns 21.

pre-decrement

--variable

Subtracts 1 from the named variable, and returns the variable's new value. For example, if variable fred is equal to 5, --fred sets fred to 4, and returns 4.

pre-increment

++variable

Adds 1 to the named variable, and returns the variable's new value. For example, if variable fred is equal to 5, ++fred sets fred to 6, and returns 6.

subtraction

first - second

Returns the difference between two numeric operands.

unary minus (negation)

-number

Returns the negative of the numeric operand.

unary plus (positive)

+number

This is a no-op, provided only for grammatical completeness.
