Math插件简介

Math插件描述

First type "math", then an empty space, then the equation. The answer will appear in the drop down menu.

You can type trigonometry too like:

math 10 + cos(rad(45)) + log(10) + PI*180 / (2^4 + atan(1))

If you press the "enter" key the result will be saved  is accessible by clicking on the toolbar icon. Only the last 30 calculations will be saved  they will be cleared when the browser is closed.

Note that (^) is a "the power of" operat,  not a bitwise operat.
And that (~) is the "negative" operat, so negative 2 is "~2"  not "2".

Suppted constants are:
Eulers constant (E), Natural log of 2 (LN2), Natural log of 10 (LN10), Base 2 log of E (LOG2E), Base 10 log of E (LOG10E), Pi (PI), Square root of 0.5 (SQRT1_2), Square root of 2 (SQRT2)

Suppted (one argument) functions are:
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cube root (cbrt(x)), cos(x), cosh(x), radians to degrees (deg(x)), E to the power of x (exp(x)), log(x), log10(x), log2(x), degrees to radians (rad(x)), sin(x), sinh(x), square root (sqrt(x)), tan(x), tanh(x).
                                

Math插件离线安装方法

1.首先用户点击谷歌浏览器右上角的自定义及控制按钮，在下拉框中选择设置。

2.在打开的谷歌浏览器的扩展管理器最左侧选择扩展程序或直接输入：chrome://extensions/

3.找到自己已经下载好的Chrome离线安装文件xxx.crx，然后将其从资源管理器中拖动到Chrome的扩展管理界面中，这时候用户会发现在扩展管理器的中央部分中会多出一个”拖动以安装“的插件按钮。

4.下载 MathChrome插件v0.1版本到本地。

5.勾选开发者模式，点击加载已解压的扩展程序，将文件夹选择即可安装插件。

注意：最新版本的chrome浏览器直接拖放安装时会出现“程序包无效CRX-HEADER-INVALID”的报错信息，参照这篇文章即可解决
