Numeric and alphabetic data are expressed by "0" (OFF) and "1" (ON) numerals in the
Basic model QCPU.
This method of expression is called "binary code" (BIN).
The hexadecimal (HEX) expression method in which BIN data are expressed in 4-bit
units, and the BCD (binary coded decimal) expression method are also possible for the
Basic model QCPU.
Real numbers may also be used. (See Section 4.8.4)
The numeric expressions for the BIN, HEX, BCD, and Decimal (DEC) notations are
shown in Table 4.1 below.
