Basic Math Functions

math.abs(x)

Calculate absolute value.

Parameters: - x - Number

Returns: - Absolute value of the number

Example:

show(`abs(-123) = `, math.abs(-123));  // Output: 123

math.sqrt(x)

Calculate square root.

Parameters: - x - Non-negative number

Returns: - Square root value

Example:

show(`sqrt(16) = `, math.sqrt(16));  // Output: 4

math.pow(x, y)

Calculate power operation.

Parameters: - x - Base - y - Exponent

Returns: - x raised to the power of y

Example:

show(`pow(2, 3) = `, math.pow(2, 3));  // Output: 8

Trigonometric Functions

math.sin(x)

Calculate sine value (in degrees).

Parameters: - x - Angle in degrees

Returns: - Sine value

Example:

show(`sin(90) = `, math.sin(90));  // Output: 1

math.cos(x)

Calculate cosine value (in degrees).

Parameters: - x - Angle in degrees

Returns: - Cosine value

Example:

show(`cos(0) = `, math.cos(0));  // Output: 1

math.tan(x)

Calculate tangent value (in degrees).

Parameters: - x - Angle in degrees

Returns: - Tangent value

Example:

show(`tan(45) = `, math.tan(45));  // Output: 1

Math Constants

math.pi()

Return the value of pi (π).

Parameters: None

Returns: - Value of π (approximately 3.14159...)

Example:

show(`π = `, math.pi());  // Output: 3.141592653589793

math.e()

Return the value of Euler's number (e).

Parameters: None

Returns: - Value of e (approximately 2.71828...)

Example:

show(`e = `, math.e());  // Output: 2.718281828459045

Extremum Functions

math.max(...args)

Calculate the maximum of multiple numbers.

Parameters: - ...args - Multiple numbers

Returns: - Maximum value

Example:

show(`max(10, 5, 20) = `, math.max(10, 5, 20));  // Output: 20

math.min(...args)

Calculate the minimum of multiple numbers.

Parameters: - ...args - Multiple numbers

Returns: - Minimum value

Example:

show(`min(10, 5, 20) = `, math.min(10, 5, 20));  // Output: 5

Random Number Functions

math.random()

Generate a random number between 0 and 1.

Parameters: None

Returns: - Random float between 0 and 1

Example:

show(`random() = `, math.random());  // Output: 0.123456...

math.randint(a, b)

Generate a random integer within a specified range.

Parameters: - a - Minimum value - b - Maximum value

Returns: - Random integer between a and b (inclusive)

Example:

show(`randint(1, 100) = `, math.randint(1, 100));  // Output: 42
