Mojo function
next_power_of_two
next_power_of_two(val: Int) -> Int
Computes the smallest power of 2 that is greater than or equal to the input value. Any integral value less than or equal to 1 will be ceiled to 1.
This operation is called bit_ceil() in C++.
Args:
- val (
Int): The input value.
Returns:
The smallest power of 2 that is greater than or equal to the input value.
next_power_of_two[type: DType, width: Int, //](val: SIMD[type, width]) -> SIMD[type, width]
Computes the smallest power of 2 that is greater than or equal to the input value for each element of a SIMD vector. Any integral value less than or equal to 1 will be ceiled to 1.
This operation is called bit_ceil() in C++.
Constraints:
The element type of the input vector must be integral.
Parameters:
- type (
DType):dtypeused for the computation. - width (
Int): SIMD width used for the computation.
Args:
- val (
SIMD[type, width]): The input value.
Returns:
A SIMD value where the element at position i is the smallest power of 2 that is greater than or equal to the integer at position i of the input value.
