/**
* @brief Method converts low precision integer types
* The method uses the next logic for conversion:
* * For unsigned types we just copy all bits to destination type (which is bigger):
* int4 [1011] -> int8 [00001011]
* * For signed types we copy all bits (except sign bit) to destination type and after
* that for negative values we set to 1 all higher bits:
* int4 [1011] -> int8 [11110011]
*
* @param src source value !!! the type must be unsigned !!!
* @param dst destination value !!! the type must be unsigned !!!
