浮点(数)
1. A form of number representation in which quantities are represented by a number multiplied by the number base raised to a power; e.g., the decimal number 397 can be written as 3.97×102,or 0.397×103。
一种表示数的形式,数目可表示为一个数乘以基数的幂次,例如,十进制数397可写成 3.97×102或0.397×103。
2.A form of number representation in a given base where a number is expressed as a mantissa multiplied by an exponent of the number base. Numbers with a very large range of magnitude, but limited precision, can be expressed with a fixed number of digits, one set of digits is allocated to the mantissa and another to the exponent.
一种按给定基数表示数的方法,其中一个数表示为尾数乘以基数的幂。一个量值很大但 精度有限的数,可用固定的数位来表示,一组数字代表尾数,另一组数字代表基数的幂数。 |
