function

ctpop

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

Counts the number of bits set in a value.

Parameters:

• ​type (DType): dtype used for the computation. Constraints: must be integral.
• ​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 bits set in the element at position i of the input value.
