They are giant, inscrutable matrices of floating point numbers that we nudge in the direction of better performance until they inexplicably start working.

它们是无法参透的大型浮点数矩阵，我们在朝着更好的性能试探着前进，直到它们莫名其妙地运行起来。

Several methods have been developed to represent floating point numbers.

已经开发了几种方法来表示浮点数。

These are called " floating point" numbers, because the decimal point can float around in the middle of number.

这些被称为“浮点”数字，因为小数点可以在数字中间浮动。

So, you have learned that in Python programming language you have 2 types of numbers, integers which are whole numbers like 10, they don't have a decimal point, and floating point numbers or floats.

所以，你已经了解到在 Python 编程语言中你有 2 种类型的数字，整数是整数，如 10，它们没有小数点，以及浮点数或浮点数。
