Operators

Using Operators

Operators are special symbols or keywords that perform operations on one or more values (operands) to produce a result. Ry supports a standard set of arithmetic, comparison, and logical operators.

Arithmetic Operators

These operators are used to perform mathematical calculations on Number types.

• + (Addition)
• - (Subtraction)
• * (Multiplication)
• / (Division)
• % (Modulo - remainder of a division)

data a = 10
data b = 3

out(a + b) # 13
out(a * 2) # 20
out(a % b) # 1

Comparison Operators

Comparison operators are used to compare two values. These expressions always evaluate to a Boolean (true or false).

• == (Equal to)
• != (Not equal to)
• < (Less than)
• > (Greater than)
• <= (Less than or equal to)
• >= (Greater than or equal to)

data score = 95
data passingScore = 70

out(score >= passingScore) # true
out("hello" == "world") # false

Logical Operators

Logical operators are used to combine or invert boolean values. They are essential for building complex conditions, especially in control flow.

• and (Logical AND)
• or (Logical OR)
• not (Logical NOT)

data hasKey = true
data doorLocked = true

data canEnter = hasKey and not doorLocked
out(canEnter) # false

Bitwise Operators

For low-level manipulation of numbers, Ry provides bitwise operators. These treat numbers as a sequence of binary bits.

• & (Bitwise AND)
• | (Bitwise OR)
• ^ (Bitwise XOR)
• ~ (Bitwise NOT)
• << (Left Shift)
• >> (Right Shift)

data a = 5  # 0101 in binary
data b = 3  # 0011 in binary

out(a & b) # 1 (0001)
out(a | b) # 7 (0111)
out(a ^ b) # 6 (0110)
out(~a)  # -6 (due to two's complement)
out(a << 1) # 10 (1010)
out(a >> 1) # 2 (0010)

Now that you know how to work with data, it's time to organize your code into reusable blocks in the Functions section.
