Hi there 👋

number_precision's Issues

四舍五入方法异常

print(NP.round(0.665, 2)); // 0.67 对的
print(NP.round(12.665, 2)); // 12.67 对的
print(NP.round(2461.5384615384614, 6)); // 错的 0.742802

number_precision: 2.0.1+1 该版本和以前版本中小数计算出现计算结果错误

在Dart文件中使用 number_precision: 2.0.1+1 该版本和以前版本，在多小数点计算的情况下会出现计算结果值错误的问题，如下图所示：

beyond boundary when transfer to integer

I run into this issue frequently but can resolve it by using the 'strip' function to reduce the character length of a "run-away decimal", however it also happens in the package where I can't change anything. In this example the times function used by the divide function will give the error.

Perhaps use BigInts rather, or strip decimals to fall into the Int range?

Great package btw, I prefer using this over the Decimal package, also algins with the npm package.

This is on number_precision: ^2.0.2+1

截取异常

print(NP.strip('0.665', precision: 2)); // 0.67 对的
print(NP.strip('12.665', precision: 2)); // 12.66 错的，为什么不是 12.67

print(NP.round(0.665, 2)); // 0.67 对的
print(NP.round(12.665,2));// 12.67 对的

number_precision: 2.0.1+1
