Arithmetic / Logic

Arithmetic / Logic

The Arithmetic / Logic module provides essential mathematical operations and logical comparisons for the SCM programming language. This module includes:

• Type checking: Functions to verify data types (int?, number?, nil?)
• Basic arithmetic: Addition (+), subtraction (-), multiplication (*), and division (/)
• Comparison operations: All standard comparison operators (>, <, >=, <=, equal?)
• Logical operations: Boolean negation (!, not) and advanced equality checks
• Mathematical functions: Min/max operations and rounding functions (floor, ceil, round)

These functions form the mathematical foundation for calculations and logical decision-making in SCM programs.

int?

tells if the value is a integer

Allowed number of parameters: 1–1

Parameters:

• value (any): value

Returns: bool

number?

tells if the value is a number

Allowed number of parameters: 1–1

Parameters:

• value (any): value

Returns: bool

+

adds two or more numbers

Allowed number of parameters: 2–1000

Parameters:

• value... (number): values to add

Returns: number

-

subtracts two or more numbers from the first one

Allowed number of parameters: 2–1000

Parameters:

• value... (number): values

Returns: number

*

multiplies two or more numbers

Allowed number of parameters: 2–1000

Parameters:

• value... (number): values

Returns: number

/

divides two or more numbers from the first one

Allowed number of parameters: 2–1000

Parameters:

• value... (number): values

Returns: number

<=

compares two numbers or strings

Allowed number of parameters: 2–2

Parameters:

• value... (any): values

Returns: bool

<

compares two numbers or strings

Allowed number of parameters: 2–2

Parameters:

Returns: bool

>

compares two numbers or strings

Allowed number of parameters: 2–2

Parameters:

• value... (any): values

Returns: bool

>=

compares two numbers or strings

Allowed number of parameters: 2–2

Parameters:

• value... (any): values

Returns: bool

equal?

compares two values of the same type, (equal? nil nil) is true

Allowed number of parameters: 2–2

Parameters:

• value... (any): values

Returns: bool

equal??

performs a SQL compliant sloppy equality check on primitive values (number, int, string, bool. nil), strings are compared case insensitive, (equal? nil nil) is nil

Allowed number of parameters: 2–2

Parameters:

• value... (any): values

Returns: bool

!

negates the boolean value

Allowed number of parameters: 1–1

Parameters:

• value (bool): value

Returns: bool

not

negates the boolean value

Allowed number of parameters: 1–1

Parameters:

• value (bool): value

Returns: bool

nil?

returns true if value is nil

Allowed number of parameters: 1–1

Parameters:

• value (any): value

Returns: bool

min

returns the smallest value

Allowed number of parameters: 1–1000

Parameters:

• value... (number|string): value

Returns: number|string

max

returns the highest value

Allowed number of parameters: 1–1000

Parameters:

• value... (number|string): value

Returns: number|string

floor

rounds the number down

Allowed number of parameters: 1–1

Parameters:

• value (number): value

Returns: number

ceil

rounds the number up

Allowed number of parameters: 1–1

Parameters:

• value (number): value

Returns: number

round

rounds the number

Allowed number of parameters: 1–1

Parameters:

• value (number): value

Returns: number
