Expression 2 Number

This is a full list of functions provided by E2's number extension. It will also include syntax for comparison operations and bitwise ops.

Example are shown here: Expression 2 Examples: Number

Table of Contents Comparison Arithmetic Assignment Bitwise

Comparison

Syntax	Example	Description
>	if ( A>8 ) {}	Greater than comparison. Returns 1 when the left value is greater than the right value.
<	if ( A<4 ) {}	Less than comparison. Returns 1 when the left value is less than the right value.
>=	if ( A>=6 ) {}	Returns 1 when the right value is either greater than or equal to the left value.
<=	if ( A<=14 ) {}	Returns 1 when the right value is either less than or equal to the left value.

Arithmetic

haha numbers go wheeeeeeee

Syntax	Example	Description
+	3 + 8	If you don't know what this does, I feel sorry for you.
-	A - B	Subtracts the right value from the left value, and returns the result.
*	C * D	Multiplies the right and left values together, and returns the result. This can also multiply vectors as a magnitude!
/	E / F	Divides the left value over the right value and returns an exact decimal answer.
%	E % F	Divides the left value over the right value, and returns the remainder of the division.
^	4 ^ N	Raises the left value to the Nth power exponent, and returns the result.

Assignment

Number variables can be reassigned a new value based on an arithmetic operator by simply appending an equal sign after it.
The format A += B, is equivalent to doing A = A + B. This works for any arithmetic operation.

There is also a shorthand form of this to increment/decrement a variable by just 1.

Syntax	Example	Description
+=	A += B - C	Sets the variable A equal to itself, plus B-C.
-=	A -= B + C	Sets the variable A equal to itself, minus B+C.
*=	A *= D	Sets A equal to A * D.
/=	A /= E	Sets A equal to A / E.
%=	A %= G	Sets A equal to A % G.
^=	A ^= H	Sets A equal to A to the power of H.

Bitwise

Developed by: asiekierka, TomyLobo (made xor), and Divran (added operators)

Bitwise operators act on numbers as if they were decimal-represented binary numbers.The individual bits of a number have operations taken against them. Wikipedia has a good explanation of each function: http://en.wikipedia.org/wiki/Bitwise_operation

Tip: You can also use N:toString(2) and S:toNumber(2) to perform bitwise manipulation using the string functions.

Function	Returns	Description
bOr(N,N)		Performs bitwise OR against the two numbers (Operator: N || N)
bAnd(N,N)		Performs bitwise AND against the two numbers (Operator: N && N)
bXor(N,N)		Performs bitwise XOR against the two numbers (Operator: N ^^ N)
bShl(N,N)		Performs bitwise shift left on the first number by the amount of the second (Operator: N << N)
bShr(N,N)		Performs bitwise shift right on the first number by the amount of the second (Operator: N >> N)
bNot(N)		Performs a binary Not
bNot(N,N)		Performs a binary Not. The second argument is the length of the number you wish to perform Not on in bits.
