General math functions

Return the maximum integer between int a and int b

int max_int(int a, int b);

Return the minimum integer between int a and int b

int min_int(int a, int b);

Clamps an integer between a high and low value

int clamp_int(int i, int low, int high);

Converts a string representing a binary number into an integer. Supports underscores as spacing

int binstr_to_int(const char *s);
 
/* Usage */
int a = binstr_to_int("10011101");
int b = binstr_to_int("1001_1101_0010_1011");

Uses bresenham’s line algorithim to generate a line in 2D space. Returns a pointer to an array of Point. The sz parameter holds the size of the array.

Point *bresenham(int x0, int y0, int x1, int y1, size_t *sz);

Works the same as bresenham() but uses the Point struct instead of int

Point *bresenham_p(Point p1, Point p2, size_t *sz);

Returns 1 if i is a power of two, otherwise returns 1.

int is_power_of_two(int i);
