Printf width specifier to maintain precision of floating-point value
...ces for an exact representation of the value if an exact representation in base 2 exists and otherwise is sufficiently large to distinguish values of type double.
I'd have to add that this is only available since C99.

Expand a random range from 1–5 to 1–7
...will run in a constant amount of time, since 1/7 is an infinite decimal in base 5. One simple solution would be to use rejection sampling, e.g.:
int i;
do
{
i = 5 * (rand5() - 1) + rand5(); // i is now uniformly random between 1 and 25
} while(i > 21);
// i is now uniformly random between 1...

How can bcrypt have built-in salts?
...tch.
Bcrypt operates in a very similar manner to more traditional schemes based on algorithms like PBKDF2. The main difference is its use of a derived key to encrypt known plain text; other schemes (reasonably) assume the key derivation function is irreversible, and store the derived key directly.
