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

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

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:

number|string): value
Returns: number|string
floor
rounds the number down
Allowed number of parameters: 1–1

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
