问题描述

如果你有一个的MSSQLServer浮动，以你怎么在.NET中映射呢？

If you have a float in MSSQLServer, to what do you map this in .NET?

你能转换为双人间或将你输数？

Can you convert it to Double or will you lose numbers?

推荐答案

SQLServer的浮动和C＃/ VB 双具有相同的重presentation。这是正确的映射。你不想做的就是地图的SQL Server 浮动为C＃/ VB 浮动因为这可能涉及亏损的precision。 SQL Server的真正映射到C＃/ VB 浮动。

SQLServer float and C#/VB double have the same representation. This is the correct mapping. What you don't want to do is map SQL Server float to C#/VB float as that may involve a loss of precision. SQL Server real maps onto C#/VB float.

T-SQL float和real类型定义可以在 MSDN 被发现。 C＃的双重定义可以在 MSDN 为好，因为可以浮动的definition 。

T-SQL float and real type definitions can be found at MSDN. C# double definition can be found at MSDN as well, as can the float definition.
