非整數值如何存儲在浮點數中(以及為什么要浮點數) (How non-integer values are stored in a float (and why it floats))

Did you ever think how computers work on floating-point numbers? I mean — where does the decimal point go? What if you’re asked in an interview?

您是否曾經想到計算機如何在浮點數上工作？ 我的意思是-小數點在哪里？ 如果在面試中被問到怎么辦？

The IEEE 754 floating-point standard defines how non-integer values are encoded in fixed-size types, like the C++ float and the JavaScript Number. It gives us five different formats — but no worries, all of them…

IEEE 754浮點標準定義了如何將非整數值編碼為固定大小的類型，例如C ++ float和JavaScript Number。 它為我們提供了五種不同的格式-不用擔心，所有這些……
