Will It Bit?

Louis Davidson wants to see what he can cast to a bit type:

There are no other textual/alpha string values that will cast to a bit value, but the numeric values that will cast to a bit are voluminous (even some that are in string format). Consider the following eight statements:

SELECT CAST(100 AS bit);
SELECT CAST(-100 AS bit);
SELECT CAST(99999999999999999999999999999999999999 AS bit);
SELECT CAST(-99999999999999999999999999999999999999 AS bit);
SELECT CAST(88.999999 AS bit);
SELECT CAST('1' AS bit);
SELECT CAST('2' AS bit);
SELECT CAST('999999' AS bit);

Danged if they didn’t all work, and all return 1.
