根据数字类型以及是否存在精度说明符，数字会转换为固定点或科学记数法的最紧凑形式。
The number is converted to the most compact of either fixed-point or scientific notation depending on the type of the number and whether a precision specifier is present.
例如，可以将数值格式化为十六进制、科学记数法或者由用户指定的标点符号分隔成组的一系列数字。
For example a numeric value can be formatted in hexadecimal scientific notation or a series of digits separated into groups with a user-specified punctuation mark.
此外，还可以使用指数记数法表示浮点型直接量，即实数后跟随字母e或E，后面加上正负号，其后再加一个整型指数。
Floating-Point literals may also be represented using exponential notation: a real number followed by the letter e(or E), followed by an optional plus or minus sign, followed by an integer exponent.
