Exponential (log, log2, log10, exp, exp2, exp10, SQRT, cur).

指数函数(log、log2、log10、exp、exp2、exp10、sqrt、cur)。

where (with pi = 3.1415... and sqrt() denoting the square root)

其中 ( pi = 3.1415...，sqrt() 表示平方根)

The third to last panel is an imaginary number.Shouldn't it be -SQRT(x)?

倒数第三张图是错的吧? 难道不应该是-√x 嘛?

SQRT square root. I'm saying, this is the name I'm going to give to this function.

就是平方根，And, this, equates, to, that。，In, this, case, sqrt，我说的是这是它的名字，我将给这个函数命名。

A more portable option is to use the standard defined style: double SQRT (double d1) throw ;.

一种更加具有可移植性的方法是，使用标准定义的风格：double sqrt (double d1) throw ；。
