Binary conversion of MySQL numbers (use of conv)

CONV (NParth from Basebook Basebook totalbase)

Convert numbers between different cardinals. Converts the number N from from_base to to_base and returns as a string. If any parameter is NULL, the return value is also NULL. The parameter N is interpreted as an integer, but it can also be specified as an integer or a string. The minimum base is 2 and the maximum base is 36. If to_base is a negative value, N is treated as a signed number. Otherwise, N is considered unsigned. CONV works at 64-bit precision.
