A real type defines a set of Numbers that can be represented with floating-point notation.
实数类型定义了一组可以以浮点记号描述的数。
UML is arguably the best notation to use with Zachman because it does not pose dependencies on other methods and, hence, can act as a point of departure into both RUP and Zachman.
UML可被证明是Zachman使用的最好符号，因为它不依赖其他方法，因此可以作为RUP和Zachman的出发点。
IEEE 754 represents floating point Numbers as base 2 decimal Numbers in scientific notation.
IEEE 754用科学记数法以底数为2的小数来表示浮点数。
The language was added in recent years to draw a clear line. It’s easy for students to point to this notation and say “Hey, Mom, I think you’re supposed to be gone now”.
这些语言可以说是划出一条明确界限，学生可以指着这些文字对家长说：“瞧，妈妈，您该走了吧。”
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.
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。
To find the common log of a number, we first write it in scientific notation with one figure to the left of the decimal point.
为了求一个数的常用对数，首先按照科学计数法把它写作小数点左面具有一位的数。
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.
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。
