String Operators

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

Symbol Type Name Description Example
Arithmetic
~ Infix Concatenation Joins the right term to the end of the left term a ~ b
~* Infix Repetition Repeats the left term by the number specified by the right term a ~* b
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
Type Casting
~ Prefix Cast Converts the term to a String ~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 string

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