i * 1.0应该将其转换为浮点数。涉及任何类型的浮点数的任何计算都会隐式转换为 extendend，然后在赋值...
t:double;arr1: array[1..5] of Double;arr2: array[1..5] of Double;const w: integer = 0;begin for i := 1 to 5 do begin arr1[i]:= arr2[i]/(w*0.6);arr2[i]:= 0;end;end;这样改就行了。1、var是定义变量的，你w: integer = 0;这是定义常量的写法。2、arr1[...

总之,在Delphi中将Double转换为Integer时,选择合适的转换函数(Trunc、Floor、Ceil或Round)并根据需要处理可能的溢出情况是非常重要的。
