数字运算符

数字运算符最简单,几乎与其他语言相同。

  • +, - ,*和/。加法,减法,乘法和除法运算符(在 VFP 中没有整数除法,可以将结果转换为带有函数 INT(),CEILING()和 FLOOR() 的整数。
  • %模数运算符。
  • ^和**。运算符的力量。他们都做同样的事情。
  • ()。分组运算符。
  • 运算符优先。订单是:
>    ( )
>    ^ (or **) 
>    / and *
>    - and +
> ```

    ? 10 / 5 + 2 && Outputs 4
    ? 2 + 10 / 5 && Outputs 4 as well. Division has precedence.
     
    * Both multiplication and division have same precedence
    * They would be interpreted from left to right.
    ? 4 * 5 / 2 + 5 && Outputs 15
    * Use parentheses whenever you are in doubt or want to be explicit
    ? ( (4 * 5) / 2 ) + 5 && Outputs 15. Explicit grouping of operations

    ? 4 * 5^2 && ^ has precedence, this is same as 4 * (5^2) = 100.
    ? (4 + 5)^2 && Using parentheses we say add 5 to 4 (9) and then square = 81.
