Operators ​

Operators are the foundation of any programming language, allowing you to perform various operations on variables and values. This page covers the syntax and usage of operators in Nuru, including assignment, arithmetic, comparison, member, and logic operators.

Assignment ​

Assuming i and v are predefined variables, Nuru supports the following assignment operators:

• i = v: which is the regular assignment operator
• i += v: which is the equivalent of i = i + v
• i -= v: which is the equivalent of i = i - v
• i *= v: which is the equivalent of i = i * v
• i /= v: which is the equivalent of i = i / v

For strings, arrays and dictionaries, the += sign operator is permissible. Example:

list1 += list2 // this is equivalent to list1 = list1 + list2

list1 += list2 // this is equivalent to list1 = list1 + list2

Arthmetic Operators ​

Nuru supports the following arithmetic operators:

• +: Additon
• -: Subtraction
• *: Multiplication
• /: Division
• %: Modulo (ie the remainder of a division)
• **: Exponential power (eg: 2**3 = 8)

Comparison Operators ​

Nuru supports the following comparison operators:

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

Member Operators ​

The member operator in Nuru is ktk. It will check if an object exists in another object:

fanya majina = ['juma', 'asha', 'haruna']

"haruna" ktk majina // kweli
"halima" ktk majina // sikweli

fanya majina = ['juma', 'asha', 'haruna']

"haruna" ktk majina // kweli
"halima" ktk majina // sikweli

Logic Operators ​

Nuru supports the following logic operators:

• &&: Logical AND. It will evaluate to true if both are true, otherwise it will evaluate to false.
• ||: Logical OR. It will evaluate to false if both are false, otherwise it will evaluate to true.
• !: Logical NOT. It will evaluate to the opposite of a given expression.

Precedence of Operators ​

Operators have the following precedence, starting from the highest priority to the lowest:

• () : Items in paranthesis have the highest priority
• !: Negation
• %: Modulo
• **: Exponential power
• /, *: Division and Multiplication
• +, +=, -, -=: Addition and Subtraction
• >, >=, <, <=: Comparison operators
• ==, !=: Equal or Not Equal to
• =: Assignment Operator
• ktk: Member Operator
• &&, ||: Logical AND and OR

Understanding operators in Nuru allows you to create complex expressions, perform calculations, and make decisions based on the values of variables.
