科学记数法(Scientific Notation)是一种表示非常大或非常小数值的方式,它允许我们将数字以10的幂的形式表示。科学记数法的格式为:a × 10^b,其中a是一个位于1和10之间的数,而b是一个整数。例如,2.5e3表示2.5乘以10的3次方,即250。 如何使用科学记数法表示数值? 在Python中,我们可以使用内置函数科学记数法(...

The built-in str() function allows you to create new strings and also convert other data types into strings: Python >>> str() '' >>> str(42) '42' >>> str(3.14) '3.14' >>> str([1, 2, 3]) '[1, 2, 3]' >>> str({"one": 1, "two": 2, "three": 3}) "{'one'...
All floating-point numbers must have a decimal part, which can be 0, which is designed to distinguish floating-point numbers from integer types. There are two kinds of decimal representation and scientific notation. Scientific numeration uses the letter e or E as a symbol for a power, with ...

For a given precision p >= 1, this rounds the number to p significant digits and then formats the result in either fixed-point format or in scientific notation, depending on its magnitude. The precise rules are as follows: suppose that the result formatted with presentation type 'e' and ...
