| SYNOPSIS |
| int last_bit(string str) |
| |
| DESCRIPTION |
| Return the number of the last set bit in bitstring <str>. |
| |
| Each character contains 6 bits. So you can store a value |
| between 0 and 63 in one character (2^6=64). Starting character |
| is the blank " " which has the value 0. The first character in |
| the string is the one with the lowest bits (0-5). |
| |
| EXAMPLES |
| string s; |
| |
| s = set_bit("", 4); s = set_bit(s, 2); |
| |
| last_bit(s) --> returns 4 |
