• ** forexponentiation, supportsfloat,int andbigint
• % forremainder (in fact not modulo, see:https://bigmachine.io/career/mod-and-remainder-are-not-the-same), supportsfloat,int andbigint
• ~~~ forbitwise NOT, supportsint andbigint
• ||| forbitwise OR, supportsint andbigint
• &&& forbitwise AND, supportsint andbigint
• ^^^ forbitwise XOR, supportsint andbigint
• << forleft shift, supportsint andbigint
• >> forright shift, supportsint andbigint
• >>> forunsigned right shift, supportsint only

Both add them to thesyntax lookup and to their corresponding section (float, int, bigint) inhttps://rescript-lang.org/docs/manual/v12.0.0/primitive-types.
