兆 = 百萬 ?

| | Comments (0)

大陸都稱 M 為兆, 詢問他們為什麼 1兆 = 1百萬, 也說不出所以然,
Google 查到這種說法源自於十進位系統, 十 百 千 万 亿 兆 京 彼此之間都差十倍, 十億為兆, 即 106
一般數學上的兆為 1012, 避免混淆, 1012用「萬億」表達.
科技上所用到的兆都指106, 如百兆網路(100M), 兆赫(MHz)等.

有些飲料都會有「鹿角菜膠」的成份, 原來它是海藻中的紅藻所提煉而成, 用來增加食品滑嫩的口感.
在還沒查資料前, 還以為它是從鹿角提煉的呢.

在 ~/.inputrc 檔增加設定如下:
# inputrc - global inputrc for libreadline
# See readline(3readline) and `info rluserman' for more information.
# Be 8 bit clean.
set meta-flag on
set input-meta on
set output-meta on
# To allow the use of 8bit-characters like the german umlauts, comment out
# the line below. However this makes the meta key not work as a meta key,
# which is annoying to those which don't need to type in 8-bit characters.
set convert-meta off
