Mojo function

bit_width

bit_width(val: Int) -> Int

Computes the minimum number of bits required to represent the integer.

Args:

  • ​val (Int): The input value.

Returns:

The number of bits required to represent the integer.

bit_width[type: DType, width: Int, //](val: SIMD[type, width]) -> SIMD[$0, $1]

Computes the minimum number of bits required to represent the SIMD vector of integer values.

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 equals to the number of bits required to represent the integer at position i of the input value.
