CONV

CONV(X, current_base, new_base)

CONV takes a string representation of an integer value, it's current_base, and the base to convert that argument to. CONV returns a new string, that represents the value in the new base. CONV is only supported for converting to/from base 2, 8, 10, and 16.

For example:

CONV('10', 10, 2) =='1010'
CONV('10', 2, 10) =='2'
CONV('FA', 16, 10) =='250'
