Mathematical Operations

Builtin

Connery is a functional programming language as such mathematical operations are no different from regular functions and are used in a style similar to polish notation.

; Addition
(+ 1 1)
; Subtraction
(- 1 1)
; Multiplication
(* 1 1)
; Division
(/ 1 1)

mod

Builtin

mod returns the result of integer division between two numbers. Useful for job interview tests.

(fun {fizzbuzz number} {
     case
     {(== 0 (mod number 15)) "FizzBuzz"}
     {(== 0 (mod number 5)) "Buzz"}
     {(== 0 (mod number 3)) "Fizz"}
     {Otherwise number}
})

pow

Builtin

pow returns the power of a number for a given exponent.

(pow 2 10)

1024

is_even

StdLib

is_even returns True (1) if the number is even, and False (0) if the number is odd.

(is_even 2)

1

is_odd

StdLib

is_odd returns False (0) if the number is even, and True (1) if the number is odd.

(is_odd 2)

0

rand

Builtin

rand returns a random number between the two numbers provided inclusive.

(rand 1 10)
(rand 1 10)
(rand 1 10)
(rand 1 10)

Equality checking

Builtin

Equality checking can be completed in the same manner as other mathematical operations, as well as greater than or less than. If the statement is true it returns True (1) otherwise it returns False (0).

; Equal to
(= 1 1)
; Greater than
(> 2 1)
; Equal to or greater than
(>= 1 2)
; Less than
(< 2 1)
; Equal to or less than
(<= 1 2)
; Not equal
(!= 1 2)
