Numerical Operators

Number Operators perform various operations on the terms specified. There are several different types of operation available.

Symbol Type Name Description Example
Arithmetic
+ Infix Addition Adds the right term to the left term to give the sum a + b
- Infix Subtraction Takes the right term away from the left term to give the difference a - b
* Infix Multiplication Multiplies the left term by the right term to give the product a * b
/ Infix Division Divides the left term by the right term to give the quotient a / b
% Infix Modulus Divides the left term by the right term and gives the remainder a % b
** Infix Exponentiation Raises the left term to the power specified by the right term a ** b
Auto-Increment/Auto-Decrement
++ Prefix Pre-increment Increments the term by 1, then returns the new value ++a
++ Postfix Post-increment Returns the term value, then increments the term by 1 a++
-- Prefix Pre-decrement Decrements the term by 1, then returns the new value --a
-- Postfix Post-decrement Returns the term value, then decrements the term by 1 a--
Bitwise
+& Infix AND Bits that are set in both left and right terms are set a +& b
+| Infix OR Bits that are set in either left or right terms are set a +| b
+^ Infix XOR Bits that are set in either left or right terms, but not both, are set a +^ b
+^ Prefix NOT All bits in the term are inverted +^ a
+< Infix Shift left Shift the bits of the left term left by the number of steps specified in the right term a +< b
+> Infix Shift right Shift the bits of the left term right by the number of steps specified in the right term a +> b
Mathematical
abs Prefix Absolute value Gives the positive numerical value of the term abs a
sin Prefix Sine Gives the sine of the term, with the term in radians sin a
cos Prefix Cosine Gives the cosine of the term, with the term in radians cos a
tan Prefix Tangent Gives the tangent of the term, with the term in radians tan a
log Prefix Logarithm Gives the base-10 logarithm of the term log a
ln Prefix Natural logarithm Gives the natural logarithm of the term ln a
Type Casting
+ Prefix Cast Converts the term to a Number, without affecting the sign +a
- Prefix Inverse cast Converts the term to a Number, and inverts the sign -a
Type Checking
is Infix IsType Checks if the value of the left term is of the type specified by the right term a is number

Each Operator will evaluate the terms provided as appropriate to the Operator value type - for instance, performing a numerical addition on two Strings will convert the Strings to Numbers first.
