回複：趁兩高手在,再請教兩個題目...最要命的是我連題目都沒看懂

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

• 這個看明白了,那remainder應該是什麽意思呢,用數學的術語解釋? -陶陶樂，樂陶陶- ♀ (0 bytes) () 12/06/2009 postreply 12:36:54
