Fixed Decimal (p,q)

Fixed Decimal (p,q) is a fixed-point number that contains p digits, where q of those digits are fraction digits. Fixed decimal values are typically used only when fraction digits are required. Fixed-point decimal values are always stored as an accurate representation of decimal fractions. The most significant digits are stored at the lowest memory address, and the byte containing the least significant digit and the sign (hexadecimal C for positive or D for negative) is stored at the highest memory address.
