  • 1.0 if the number is positive, +0.0 or INFINITY
  • -1.0 if the number is negative, -0.0 or NEG_INFINITY
  • NAN if the number is NAN

Returns true if, and only if, all elements are finite. If any element is either NaN, positive or negative infinity, this will return false.

Returns true if any elements are NaN.

Performs is_nan on each element of self, returning a vector mask of the results.

In other words, this computes [x.is_nan(), y.is_nan(), z.is_nan(), w.is_nan()].

Computes the squared length of self.

This is faster than length() as it avoids a square root operation.

Computes 1.0 / length().

For valid results, self must not be of length zero.

Computes the Euclidean distance between two points in space.

Returns self normalized to length 1.0.

For valid results, self must not be of length zero, nor very close to zero.

See also Self::try_normalize and Self::normalize_or_zero.

Panics

Will panic if self is zero length when glam_assert is enabled.

Returns self normalized to length 1.0 if possible, else returns None.

In particular, if the input is zero (or very close to zero), or non-finite, the result of this operation will be None.

See also Self::normalize_or_zero.

Returns self normalized to length 1.0 if possible, else returns zero.

In particular, if the input is zero (or very close to zero), or non-finite, the result of this operation will be zero.

See also Self::try_normalize.

Returns whether self is length 1.0 or not.

Uses a precision threshold of 1e-6.

Returns the vector projection of self onto rhs.

rhs must be of non-zero length.

Panics

Will panic if rhs is zero length when glam_assert is enabled.

Returns the vector rejection of self from rhs.

The vector rejection is the vector perpendicular to the projection of self onto rhs, in rhs words the result of self - self.project_onto(rhs).

rhs must be of non-zero length.

Panics

Will panic if rhs has a length of zero when glam_assert is enabled.

Returns the vector projection of self onto rhs.

rhs must be normalized.

Panics

Will panic if rhs is not normalized when glam_assert is enabled.

Returns the vector rejection of self from rhs.

The vector rejection is the vector perpendicular to the projection of self onto rhs, in rhs words the result of self - self.project_onto(rhs).

rhs must be normalized.

Panics

Will panic if rhs is not normalized when glam_assert is enabled.

Returns a vector containing the nearest integer to a number for each element of self. Round half-way cases away from 0.0.

Returns a vector containing the largest integer less than or equal to a number for each element of self.

Returns a vector containing the smallest integer greater than or equal to a number for each element of self.

Returns a vector containing the fractional part of the vector, e.g. self - self.floor().

Note that this is fast but not precise for large numbers.

Returns a vector containing e^self (the exponential function) for each element of self.

Returns a vector containing each element of self raised to the power of n.

Returns a vector containing the reciprocal 1.0/n of each element of self.

Performs a linear interpolation between self and rhs based on the value s.

When s is 0.0, the result will be equal to self. When s is 1.0, the result will be equal to rhs. When s is outside of range [0, 1], the result is linearly extrapolated.

Returns true if the absolute difference of all elements between self and rhs is less than or equal to max_abs_diff.

This can be used to compare if two vectors contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

For more see comparing floating point numbers.

Returns a vector with a length no less than min and no more than max

Panics

Will panic if min is greater than max when glam_assert is enabled.

Returns a vector with a length no more than max

Returns a vector with a length no less than min

Fused multiply-add. Computes (self * a) + b element-wise with only one rounding error, yielding a more accurate result than an unfused multiply-add.

Using mul_add may be more performant than an unfused multiply-add if the target architecture has a dedicated fma CPU instruction. However, this is not always true, and will be heavily dependant on designing algorithms with specific target hardware in mind.

Creates a 2D vector containing [angle.cos(), angle.sin()]. This can be used in conjunction with the rotate method, e.g. Vec2::from_angle(PI).rotate(Vec2::Y) will create the vector [-1, 0] and rotate Vec2::Y around it returning -Vec2::Y.

Returns the angle (in radians) between self and rhs.

The input vectors do not need to be unit length however they must be non-zero.

Returns a vector that is equal to self rotated by 90 degrees.

The perpendicular dot product of self and rhs. Also known as the wedge product, 2D cross product, and determinant.

Returns rhs rotated by the angle of self. If self is normalized, then this just rotation. This is what you usually want. Otherwise, it will be like a rotation with a multiplication by self’s length.

Casts all elements of self to f32.

Casts all elements of self to i32.

Casts all elements of self to u32.
