值对于小数而言太大或太小 [英] Value was either too large or too small for a Decimal

问题描述

我有以下代码:

double shortfall = GetSomeNumber(); //3.3588548831176006E+29

if (shortfall > 0)
{
  returnValue = Convert.ToDecimal(shortfall);
}

这会产生上述错误.

有人可以帮我吗?

推荐答案

嗯，这很不言自明.

decimal.MaxValue 是79,228,162,514,264,337,593,543,950,335-您的数字大于此数字.

decimal.MaxValue is 79,228,162,514,264,337,593,543,950,335 - your number is bigger than this.

尽管 decimal 的精度比 double 更高，但 double 的范围更大-它可以处理非常非常大的非常非常小数字.

Although decimal has a finer precision than double, double has a bigger range - it can handle very, very large and very, very small numbers.

现在，如果您能告诉我们您真正想做什么，我们可以尝试帮助您找到解决方案...混用 double 和 decimal很少是一个好主意，说实话.

Now, if you could tell us what you're really trying to do, we could try to help find a solution... it's rarely a good idea to mix double and decimal, to be honest.
