value_min_bits
value_min_bits(n,size) Returns the smallest number of bits that can be used to store the given value.
/*
** Usage:
** value_min_bits(n,size)
**
** Arguments:
** n value, positive integer
** size word size, positive integer (optional)
**
** Returns:
** the smallest number of bits that can be used to store the given value,
** if a word size is given, the value returned is expressed in words
**
** Example:
** value_min_bits(1000) == 10 bits
** value_min_bits(1000,8) == 2 bytes
