Returns

ctdbGetFieldPrecision() returns the field precision (maximum number of digits).

CT_MONEY:

Based on a four-byte signed integer, the maximum value for CT_MONEY is 21474836.47, which gives it a precision of 9 and a scale of 2 (although it appears to be 10 digits, values over precision 9 are not entirely within the boundaries). If you call ctdbGetFieldPrecision() on such a field, it returns 9 by definition.
