摘要:PURPOSE:To express a numeral clo to 1 with high accuracy, by attaining mutual conversion with an exponential part variable length floating decimal point reprenting value and an exponential part fixed length floating decimal point reprenting value where the length of the exponential part depends on the length of
''0'' or ''1'' train of the 1st half. CONSTITUTION:A mantissa register 12, a floating fraction register 11, an exponenial register 13, a counter 14, an FF15 and a two-input logical circuit
16 and the like are provided. If the length of the shift register 11 is denoted by k+1 bits,
a right k bits excluding a code bit 17 is given in the shift register, and every time a trigger
31 for shift left, for example, is given, the bit is shifted left by one bit and every time a trigger 32 of shift right is given, the bit is shifted right by one bit. Further, the mantissa register 12 reprents a shi
ft register having k-bit length. Thus, the mutual conversion is attained with the exponential variable length floating decimal point reprenting value and the exponential fixed length floating decimal point reprenting value where the length of the exponential part depends on the length of ''0'' or ''1'' are the 1st half.炝土豆丝的做法
