			As of [https://kolmafia.us/threads/16180-when-parsing-a-bounty-object-in-ash-make-case-insensitive-string-compariso.18981/ r16180], the equality (<code>==</code>) and inequality (<code>!=</code>) operators compare strings case-sensitively.

			The "approximately equal" operator (<code>≈</code>) was introduced in [https://kolmafia.us/threads/16284-add-an-ash-operator-to-perform-an-approximately-equal-comparison.19116/ r16284]. When comparing two strings, it compares them case-insensitively. When comparing other data types, it behaves like the equality operator (<code>==</code>).

Bale: r8971 allows logical operators to accept boolean operands

	==Bitwise Operators==		==Bitwise Operators==

	The following mathematical operators are used for operating on the bits of integers. The operands ~~must~~ be ~~integers; no coercion is allowed:~~		The following mathematical operators are used for operating on the bits of integers. The logical operators (&, \|, ^) work either with booleans or integers while the others operate upon integers only. If the operands are booleans, then result will also be a boolean.
