[英]Need help converting a Multi-Cell Excel formula to basic pseudo code
I don't think the whole spreadsheet is relevant here (Hope I am not wrong) but essentially I am working with some financial figures and need to work out a "Cumulative Cost". 我认为整个电子表格在这里不相关(希望我没错),但从本质上讲,我正在处理一些财务数据,并且需要计算出“累积成本”。 The spreadsheet is correct, but I don't understand the maths of the formula, so I hope somebody can break it down into BODMAS or pseudo code or something (or even Java which it will ultimately be.) 电子表格是正确的,但是我不了解该公式的数学原理,因此我希望有人可以将其分解为BODMAS或伪代码之类的东西(甚至最终可以是Java的东西)。
{=(PRODUCT($D$4:D7/100+1)-1)*100}
{=(PRODUCT($D$4:D8/100+1)-1)*100}
{=(PRODUCT($D$4:D9/100+1)-1)*100}
etc.. 等等..
I think I only needed to supply one formula, but just giving a few more for context. 我认为我只需要提供一个公式,而仅提供一些更多的上下文即可。
So the formulas above are found in column E: Screenshot of Table 因此,以上公式可在E列中找到: 表格的屏幕截图
Thanks! 谢谢!
The part of the formula, /100+1
, converts from a percentage change. 公式的一部分/100+1
从百分比变化转换。 The part, -1)*100
, converts to a percentage change. -1)*100
部分转换为百分比变化。 PRODUCT()
multiplies the numbers togther. PRODUCT()
将数字相乘。
double d[12], e[12]; // input and output arrays, respectively
double p = 1.0; // to accumulate the product
for (i = 0; i < 12; i++)
{
p = p * ((d[i] / 100) + 1); // convert from percentage and multiply
e[i] = (p - 1) * 100; // convert to percentage
}
Additional (
and )
and spaces added for clarity. 为了清楚起见,添加了其他(
和)
和空格。
