Floatingpoint is a very similar concept, except that computers use binary rather than decimal as their base.
浮点是一个非常类似的概念,除了计算机使用二进制而不是十进制作为基础。

These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floatingpoint and 64-bit double precision floatingpointbinary-decimal Numbers.
它们都依据IEEE 754标准,该标准为32位浮点和64位双精度浮点二进制小数定义了二进制标准。

Because internally, computers use a format (binaryfloating-point) that cannot accurately represent a number like 0.1, 0.2 or 0.3 at all.
