在第2部分中，我主要关注这样一些函数，它们的目的是操作浮点数，而不是抽象实数。

Here in Part 2, I focus on the functions that make sense only when you realize that they're designed for operating on floating-point Numbers instead of abstract real Numbers.

在第2部分，我将探讨专为操作浮点数(与抽象实数相反)而设计的函数。

In Part 2, I'll explore the functions more designed for operating on floating point Numbers as opposed to abstract real Numbers.

单复变量包含实数和虚数两部分，针对两个实值函数n(x) 和 v(x)的表达式为：b(x) = n(x) + iv(x)。

fullprof A complex variable has real and imaginary parts written in the form b(x) = n(x) + iv(x) for two real-valued functions n(x) and v(x)
