非整数值如何存储在浮点数中(以及为什么要浮点数) (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?

您是否曾经想到计算机如何在浮点数上工作？ 我的意思是-小数点在哪里？ 如果在面试中被问到怎么办？

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…
