# `MAX(a, b)` - macro
Returns the bigger one of the given values.

# `MIN(a, b)` - macro
Returns the smaller one of the given values.

# `CEIL_TO(a, b)` - macro
Aligns **_a_** upwards to **_b_**.
Example: `CEIL_TO(13, 8)` would return 16, because 16 is the next higher multiple of 8 after 13.

# `FLOOR_TO(a, b)` - macro
Aligns **_a_** downwards to **_b_**.
Example: `FLOOR_TO(13, 8)` would return 8, because 8 is the next smaller multiple of 8 before 13.

# `position_T` - struct
This describes a position in 2D space.

| Name | Description                  |
|------|------------------------------|
| x    | X coordinate of the position |
| y    | Y coordinate of the position |


# `pow(base, exponent)` - function (uint64_t)
Returns the power of `base ^ exponent`.

# `abs(number)` - function (uint64_t)
Returns the absolute value of **_number_**.

# `octal_string_to_int(string, size)` - function (uint64_t)
Converts a base-8 **_string_** with length **_size_** into an integer and returns it.
