function

countr_zero

countr_zero(val: Int) -> Int

Counts the number of trailing zeros for an integer.

Args:

• ​val (Int): The input value.

Returns:

The number of trailing zeros of the input.

countr_zero[type: DType, simd_width: Int](val: SIMD[type, simd_width]) -> SIMD[$0, $1]

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

Constraints:

The element type of the input vector must be integral.

Parameters:

• ​type (DType): dtype used for the computation.
• ​simd_width (Int): SIMD width used for the computation.

Args:

• ​val (SIMD[type, simd_width]): The input value.

Returns:

A SIMD value where the element at position i contains the number of trailing zeros at position i of the input value.
