Constants in float.inc

List of constants

Different methods of rounding#

enum floatround_method {
    floatround_round = 0,
    floatround_floor,
    floatround_ceil,
    floatround_tozero
};

Different units of measurement for angles#

enum anglemode {
    radian = 0,
    degrees,
    grades
};

Return the angle of a sine, cosine or tangent. The output angle may be in radians, degrees, or grades.#
