Assignment

Operator	Compatible types	Description
=	All	Assigns the right-hand side value to the left-hand side, and returns the right-hand side value: ** ** var x = 45.6; ** ** Note that irScript values obey CLR assignment semantics (value types assign-by-value, reference types assign-by- reference… ScriptObject, ScriptCollection, and ScriptFunction are all reference types).
+ =	Integer, Decimal, Text	For numerics, adds the lhs and rhs values and assigns the result to lhs. For text values, concatenates lhs with rhs and assigns the result to lhs. The resulting value is returned: ** ** var x = 45.6; x += 10;
-=	Integer, Decimal	Subtracts the lhs and rhs values and assigns the result to lhs. The resulting value is returned: ** ** var x = 45.6; x -= 10;
*=	Integer, Decimal	Multiplies the lhs and rhs values and assigns the result to lhs. The resulting value is returned: var x = 45.6; x -= 10;
/=	Integer, Decimal	Divides the lhs value by the rhs value and assigns the result to lhs. The resulting value is returned: var x = 45.6; x /= 10;
%=	Integer, Decimal	Divides the lhs value by the rhs value and assigns the remainder to lhs. The resulting value is returned: var x = 45; x %= 10;
&=	Integer	Performs a bitwise 'and' operation between lhs and rhs, and assigns the value to lhs. The resulting value is returned: ** ** var x = 4; x &= 3;
**	=**	Integer
^=	Integer	Performs a bitwise 'xor' operation between lhs and rhs, and assigns the value to lhs. The resulting value is returned: ** ** var x = 4; x ^= 3;
<<=	Integer	Shifts the lhs value by rhs bits to the left, and assigns the value to lhs. The resulting value is returned: ** ** var x = 45; x <<= 2;
>>=	Integer	Shifts the lhs value by rhs bits to the right, and assigns the value to lhs. The resulting value is returned: ** ** var x = 45; x >>= 2;
