====== math ====== General math functions ===== Functions ===== ===== max_int ===== Return the maximum integer between ''%%int a%%'' and ''%%int b%%'' int max_int(int a, int b); ===== min_int ===== Return the minimum integer between ''%%int a%%'' and ''%%int b%%'' int min_int(int a, int b); ===== clamp_int ===== Clamps an integer between a high and low value int clamp_int(int i, int low, int high); ===== binstr_to_int ===== 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"); ===== bresenham ===== 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); ===== bresenham_p ===== Works the same as ''%%bresenham()%%'' but uses the ''%%Point%%'' struct instead of ''%%int%%'' Point *bresenham_p(Point p1, Point p2, size_t *sz); ===== is_power_of_two ===== Returns ''%%1%%'' if ''%%i%%'' is a power of two, otherwise returns ''%%1%%''. int is_power_of_two(int i);
