Operators

अंकगणितीय, तुलना व तार्किक ऑपरेटर

Arithmetic

Operator	Meaning	Example	Result
+	Addition; joins strings; joins two lists	10 + 5	15
-	Subtraction; unary minus	10 - 15	-5
*	Multiplication	4 * 2.5	10
/	Division (always true division)	7 / 2	3.5
%	Remainder (sign follows the left side)	-7 % 3	-1

-, *, / and % work on numbers only. + adds two numbers, joins two lists, or, when either side is a string, joins text. Any other combination is a runtime error.

Comparison

Operator	Meaning	Example	Result
==	Equal	2 + 2 == 4	खरे
!=	Not equal	"अ" != "ब"	खरे
>	Greater than	10 > 5	खरे
<	Less than	10 < 5	खोटे
>=	Greater than or equal	5 >= 5	खरे
<=	Less than or equal	4 <= 3	खोटे

== and != work on any values. Values of different kinds are never equal, and lists are compared element by element.
>, <, >=, <= need two numbers or two strings.

Logical

Operator	Meaning
आणि	AND: true when both sides are true
किंवा	OR: true when at least one side is true
नाही	NOT: reverses a value (unary)

आणि and किंवा are short-circuit operators: the right side is evaluated only when the left side does not already decide the result. They return the deciding value itself.

short_circuit.mr

कार्य तपासा() {
    छापा("उजवी बाजू तपासली")
    परत खरे
}

छापा(खोटे आणि तपासा())
छापा(खरे किंवा तपासा())
छापा(खरे आणि तपासा())
छापा(0 किंवा "पर्याय")

Output (आउटपुट)

खोटे
खरे
उजवी बाजू तपासली
खरे
पर्याय

Short-circuiting also lets a condition guard the expression after it:

guard.mr

चल यादी = []
जर लांबी(यादी) > 0 आणि यादी[0] == 5 तर {
    छापा("पहिली संख्या 5")
} नाहीतर {
    छापा("तपासले नाही")
}

Output (आउटपुट)

तपासले नाही

The order in which operators apply is described in Operator Precedence.
