回复：趁两高手在,再请教两个题目...最要命的是我连题目都没看懂

Given : s/t=64.12
By definition of the remainder, and let remainder = R
S = T * 64.12 = 64 T + 0.12 T = 64 T + R

Thus,

0.12 T = R
T = R/0.12, and T must be an integer
try plug 2, 4 ,8, 20. 45

you will find T is an integer only when R = 45

Thus,
the remainder is
45

• 这个看明白了,那remainder应该是什么意思呢,用数学的术语解释? -陶陶乐，乐陶陶- ♀ (0 bytes) () 12/06/2009 postreply 12:36:54
