Module OgamlMath.Vector2fs

Operations on immutable vectors of 2 floats represented in polar coordinates

This module defines the vector2fs type and various operations on it.

exception Vector2fs_exception of string

Raised when an error occurs (usually a division by zero)

type t = {r : float; t : float}

Type of immutable vectors of 2 floats represented in polar coordinates

`r : float`	Signed radius
`t : float`	Theta angle. An angle of 0 corresponds to a vector pointing towards positive X.

val zero : t

Zero vector

val unit_x : t

Unit x vector

val unit_y : t

Unit y vector

val prop : float -> t -> t

Multiplies a vector by a scalar

val div : float -> t -> t

Divides a vector by a scalar. Raises Vector2fs_exception if the scalar is zero.

val to_cartesian : t -> Vector2f.t

Converts a vector represented in polar coordinates to a vector represented in cartesian coordinates
See : OgamlMath.Vector2f

val from_cartesian : Vector2f.t -> t

Converts a vector represented in cartesian coordinates to a vector represented in polar coordinates
See : OgamlMath.Vector2f

val norm : t -> float

Computes the norm of a vector

val normalize : t -> t

Normalizes a vector. Raises Vector2fs_exception if the vector is zero.

val print : t -> string

Returns a pretty-printed string (not for serialization)
