Dim x as Decimal = 100.0m 是否隐式地从双精度转换为十进制? [英] Does Dim x as Decimal = 100.0m do a cast from double to decimal implicitly?

问题描述

如果我有代码:

Dim x as Decimal = 100.0m

它是否隐式地从双精度转换为小数.我将如何在 vb.net 中明确地执行此操作?

Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?

推荐答案

我想你想要:

Dim x as Decimal = 100.0d

C# 中的十进制文字是 m，但在 vb.net 中是 d.这不会产生任何铸造.要将 double 转换为小数(r 是 vb.net 中的 double 文字)，您可以说:

The decimal literal in C# is m, but is d in vb.net. This produces no casting whatsoever. To cast a double to a decimal (r is the double literal in vb.net) you could say:

Dim x as Decimal = CType(100r, Decimal)
Dim x as Decimal = CType(100.0, Decimal)
