描述 Fractions in octal (base 8) notation can be expressed exactly in decimal notation. For example, 0.75 in octal is 0.953125 (7/8 + 5/64) in decimal. All octal numbers of n digits to the right of the octal point can be expressed in no more than 3n de…

刚开始做这题时,用的是0.75[8]=(7/8+5/64)[10]这个,但是总是WA…………无语了…… 后来看别人的解题报告,知道了另外一个就是0.75[8]=((5/8+7)/8)[10],从低位向高位计算 ;}…
