Creates a vector with all elements set to 1.0
.
Creates a vector from the elements in if_true
and if_false
, selecting which to use
for each element of self
.
A true element in the mask uses the corresponding element from if_true
, and false
uses the element from if_false
.
Returns a vector containing the mininum values for each element of self
and other
.
In other words this computes [self.x.max(other.x), self.y.max(other.y), ..]
.
Returns a vector containing the maximum values for each element of self
and other
.
In other words this computes [self.x.max(other.x), self.y.max(other.y), ..]
.
Component-wise clamping of values, similar to [std::f32::clamp
].
Each element in min
must be less-or-equal to the corresponing element in max
.
If the glam-assert
feature is enabled, the function will panic if the contract is not
met, otherwise the behavior is undefined.
Returns the horizontal minimum of self
.
In other words this computes min(x, y, ..)
.
Returns the horizontal maximum of self
.
In other words this computes max(x, y, ..)
.
Returns a vector mask containing the result of a ==
comparison for each element of
self
and other
.
In other words, this computes [self.x == other.x, self.y == other.y, ..]
for all
elements.
Returns a vector mask containing the result of a !=
comparison for each element of
self
and other
.
In other words this computes [self.x != other.x, self.y != other.y, ..]
for all
elements.
Returns a vector mask containing the result of a >=
comparison for each element of
self
and other
.
In other words this computes [self.x >= other.x, self.y >= other.y, ..]
for all
elements.
Returns a vector mask containing the result of a >
comparison for each element of
self
and other
.
In other words this computes [self.x > other.x, self.y > other.y, ..]
for all
elements.
Returns a vector mask containing the result of a <=
comparison for each element of
self
and other
.
In other words this computes [self.x <= other.x, self.y <= other.y, ..]
for all
elements.
Returns a vector mask containing the result of a <
comparison for each element of
self
and other
.
In other words this computes [self.x < other.x, self.y < other.y, ..]
for all
elements.
Creates a vector from the first N values in slice
.
Panics
Panics if slice
is less than N elements long.
Writes the elements of self
to the first N elements in slice
.
Panics
Panics if slice
is less than N elements long.
Returns a vector containing the absolute value of each element of self
.
Returns a vector with elements representing the sign of self
.
1.0
if the number is positive,+0.0
orINFINITY
-1.0
if the number is negative,-0.0
orNEG_INFINITY
NAN
if the number isNAN
Returns true
if, and only if, all elements are finite. If any element is either
NaN
, positive or negative infinity, this will return false
.
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.
Compute the squared 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
.
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 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 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 other
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 other
.
Returns true if the absolute difference of all elements between self
and other
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
Returns a vector with a length no more than max
Returns a vector with a length no less than min
Returns the angle (in radians) between self
and other
.
The input vectors do not need to be unit length however they must be non-zero.
