(vb.net) rounding to 2 decimal places
提问by Mr Beanstar
I am creating a program for a project that will help me learn visual basic. But when I work out how much a certain material is worth with dimensions. It come out with more than two decimal places. I know how to use math.floor function but it doesn't round to 2 decimal places.
我正在为一个项目创建一个程序，它将帮助我学习视觉基础。但是当我计算出某种材料在尺寸上的价值时。它出来的小数点多于两位。我知道如何使用 math.floor 函数，但它不会四舍五入到小数点后两位。
Does anyone know what function I should use to round to two decimal places?
有谁知道我应该使用什么函数来四舍五入到两位小数？
