Question

十进制转二、八、十六进制

Answer 1

二进制 : 623/2 = 311 余数是 1 311/2 = 155 余数是 1 155/2 = 77 余数是 1 77/2 = 38 余数是 1 38/2 = 19 余数是 0 19/2 = 9 余数是 1 9/2 = 4 余数是 1 4/2 = 2 余数是 0 2/2 = 1 余数是 0 故 623 (base 10) = 1001101111 (base 2) 0.513 * 2 = 0.026 + 1 0.026 * 2 = 0.052 + 0 0.052 * 2 = 0.104 + 0 0.104 * 2 = 0.208 + 0 0.208 * 2 = 0.416 + 0 0.416 * 2 = 0.832 + 0 0.832 * 2 = 0.664 + 1 0.664 * 2 = 0.328 + 1 故 0.513 (base 10) = 0.10000011... (base 2) 623.513 (base 10) = 1001101111.10000011.. (base 2) 八进制/十六进制的做法一样
只是由 2 改为 8/16 便可. 623.513 (base 10) = 1157.4065... (base 8) 623.513 (base 10) = 26F.8353... (base 16)
