Binary operations
Elementwise bit operations
  |  Compute the bit-wise AND of two arrays element-wise.  |  
  |  Compute the bit-wise OR of two arrays element-wise.  |  
  |  Compute the bit-wise XOR of two arrays element-wise.  |  
  |  Compute bit-wise inversion, or bit-wise NOT, element-wise.  |  
  |  Shift the bits of an integer to the left.  |  
  |  Shift the bits of an integer to the right.  |  
Bit packing
  |  Packs the elements of a binary-valued array into bits in a uint8 array.  |  
  |  Unpacks elements of a uint8 array into a binary-valued output array.  |  
Output formatting
  |  Return the binary representation of the input number as a string.  |
