Mojo function

count_leading_zeros

count_leading_zeros(val: Int) -> Int

Counts the number of leading zeros of an integer.

Args:

  • ​val (Int): The input value.

Returns:

The number of leading zeros of the input.

count_leading_zeros[type: DType, width: Int, //](val: SIMD[type, width]) -> SIMD[type, width]

Counts the per-element number of leading zeros in a SIMD vector.

Constraints:

The element type of the input vector must be integral.

Parameters:

  • ​type (DType): DType used 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 contains the number of leading zeros at position i of the input value.
