# `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.
|
||

# `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.
