The "e", "e -", "e", or "e -" formats indicate that a sign character should only precede negative exponents.
或“e-”格式指示符号字符仅置于负指数前面。
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.
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。
