Long integer variables range from -2147483648 to 2147483647. If you assign a floating-point value to a long integer variable, the decimal places are rounded to the next integer. Long integer variables are rapidly calculated in procedures and are suitable for counter variables in loops for large values. A long integer variable requires four bytes of memory. &quot; & &quot; is the type-declaration character.
长整数变量的范围从 -2147483648 到 2147483647。如果向长整数变量指定浮点数值，小数部分将被转换成下一个整数。长整数变量在过程中的计算速度非常快，适合用作大值循环中的计数器变量。长整数变量需要四个字节的内存。其类型声明字符是“ & ”。
