什么是小数秒？ [英] what is a fractional second?

问题描述

我正在尝试了解什么是小数秒的。我发现一个小数秒，这里：

I am trying to understand what a fractional second is. I found a fractional second,here:

double uhd::time_spec_t::get_frac_secs  (   void        )    const
     Get the fractional part of the time in seconds.

Returns:
     the fractional seconds

究竟是什么分数秒表示为双重？有人可以给我一个示例值，如何翻译成秒？

What exactly is a fractional second represented as a double? Can someone give me an example value and how that translates in to seconds?

推荐答案

小数第二是时间的一部分不是一个整数。所以如果你有一个时间像 12345678.9 小数秒是 0.9

Fractional second is the part of the time that is not an integer. So if you have a time like 12345678.9 the fractional second is 0.9
