Programming language Chora: Operators
Chora provides a rich set of buildin operators, you use to form arithmeticlogical expressions. The exact function of an operator depends on the data types of the operands involved in the operation. For example, the + (plus) operator will compute an arithmetic addition when used with two int32 operands, and a string concatenation when used with two string operands.
Depending on the number of operands, the operators are classified as unary or binary. Unary operators are always applied on a single operand. Binary operators, in turn, involve two operands into the expression. Following operators are available. Please remind, the exact function of an operator results from the data types of the involved operands. For details see the description of the respective operator:

Operator precedence
Expressions in Chora are generally evaluated from left to right, whereby partial expressions enclosed in parentheses ( ... ) are evaluated first, so that the result of the partial expression can be used in the overall expression as operand. If the parentheses are missing, the order of evaluation within a complex expression is determined by the following precedence of operators:
Operators 
Priority 

postfix ++  
highest 
unary +  ~, prefix ++  

* / % 

+  

<< >> 

< <= > >= 

== != 

& 

^ 

 

&& 

 

?: 

= += = *= /= %= <<= >>= &= = ^= 
lowest 
The above table means that in an expression, all unary operators are evaluated first followed by the *, / and % operators. Partial expressions that use a logical OR operator  are, on the other hand, evaluated last. This order can be changed explicitly by the programmer through the use of parentheses. As mentioned above, an expression in parentheses is always evaluated first. The following example demonstrates the effect:
var int32 result1 = 123 + 456 * 789; // result1 = 359907 var int32 result2 = ( 123 + 456 ) * 789; // result2 = 456831
