- --or-- -= Subtract; p 150.
* --or-- *= Multiply and return lower 32 bits (signed); p 153.
** --or-- **= Multiply and return upper 32 bits (signed); p 153.
/ --or-- /= Divide (signed); p 154.
// --or-- //= Modulus (signed); p 154.

>< --or-- ><= Bitwise: Reverse; p 163.
& --or-- &= Bitwise: AND; p 164.
| --or-- |= Bitwise: OR; p 165.
^ --or-- ^= Bitwise: XOR; p 165.
AND --or-- AND= Boolean: AND (promotes non-0 to -1); p 167.
OR --or-- OR= Boolean: OR (promotes non-0 to -1); p 168.
= = --or-- = = = Boolean: Is equal; p 169.
<> --or-- <>= Boolean: Is not equal; p 170.
