因为 - toFixed - 方法返回一个字符串。
Because the - toFixed - method returns a string.

当你想将变量用作数字时使用eval()返回
数字
when you want to use the variable as a number use eval() to return a
number

当你想使用变量作为数字时使用eval()来表示
返回一个数字
when you want to use the variable as a number use eval() to
return a number
不,谢谢,我会使用一元加运算符,数字构造函数
作为函数,parseInt或parseFloat调用,具体取决于
情况。 - eval - 函数将是使用
的绝对最差的方法,特别是当它的行为是不可预测的时,只要它的
参数是一个不代表数字的字符串。 br />
No thanks, I will use the unary plus operator, the Number constructor
called as a function, parseInt or parseFloat, depending on the
situation. The - eval - function would be the absolute worst method to
use, particularly as its behaviour is unpredictable whenever its
argument is a string that does not represent a number.
