Function broadcast_array_div 

Source 
pub fn broadcast_array_div(
    lhs: impl Into<ArrayV>,
    rhs: impl Into<ArrayV>,
    null_mask: Option<&Bitmask>,
) -> Result<Array, MinarrowError>
Expand description

Broadcast division: lhs / rhs with automatic scalar expansion.

If one operand has length 1 and the other has length N, the scalar operand will be broadcast (repeated) to match the array operand’s length.

§Examples

  • Array / Scalar: [10, 20, 30] / [2] = [5, 10, 15]
  • Scalar / Array: [100] / [2, 4, 5] = [50, 25, 20]
  • Array / Array: [10, 20, 30] / [2, 4, 5] = [5, 5, 6]

§Errors

  • Returns KernelError::LengthMismatch if lengths are incompatible
  • Returns KernelError::UnsupportedType for unsupported type combinations
  • Returns KernelError::DivideByZero for division by zero (integer arrays)
