## Constant: MUL
Description: Truncated integer multiplication \(signed or unsigned\): input=\(N, N\), output=N
 It is bitwise\-equivalent to an unsigned truncated multiply \(operator [#MUL_U](#MUL_U)\) Use preferably for signed operations, as it will help with type propagation.

## Constant: PAR
Description: Standard parity operator: single operand, single\-bit result; result is 1 if number of bits \(in operand\) set to 1 is even.
 Cannot be translated to a simple operator, for convenience only. It will need ad\-hoc translators in C.
