struct FastDiv[type: DType]
Implements fast division for a given type.
This struct provides optimized division by a constant divisor, replacing the division operation with a series of shifts and multiplications. This approach significantly improves performance, especially in scenarios where division is a frequent operation.

Methods
__init__
@implicit
__init__(divisor: Int = 1) -> Self
Initializes FastDiv with the divisor.
Constraints:
ConstraintError: If the bitwidth of the type is > 32.
Args:
- divisor (
Int): The divisor to use for fast division. Defaults to 1.
__rtruediv__
__rtruediv__(self, other: SIMD[_uint_type_of_width[::Int](), 1]) -> SIMD[_uint_type_of_width[::Int](), 1]
Divides the other scalar by the divisor (true division).
Uses the fast division algorithm.
Args:
- other (
SIMD[_uint_type_of_width[::Int](), 1]): The dividend.
Returns:
The result of the division.
__rmod__
__rmod__(self, other: SIMD[_uint_type_of_width[::Int](), 1]) -> SIMD[_uint_type_of_width[::Int](), 1]
Computes the remainder of division.
Args:
- other (
SIMD[_uint_type_of_width[::Int](), 1]): The dividend.
Returns:
The remainder.
__rdiv__
__rdiv__(self, other: SIMD[_uint_type_of_width[::Int](), 1]) -> SIMD[_uint_type_of_width[::Int](), 1]
Divides the other scalar by the divisor.
Args:
- other (
SIMD[_uint_type_of_width[::Int](), 1]): The dividend.
Returns:
The result of the division.
__divmod__
__divmod__(self, other: SIMD[_uint_type_of_width[::Int](), 1]) -> Tuple[SIMD[_uint_type_of_width[::Int](), 1], SIMD[_uint_type_of_width[::Int](), 1]]
Computes both quotient and remainder.
Args:
- other (
SIMD[_uint_type_of_width[::Int](), 1]): The dividend.
Returns:
A tuple containing the quotient and remainder.
