[VB.NET] Single & Double

---vb.net single & double---
single的精度的问题
先简单说明一下:项目里面有个金额的内容,一开始使用的single,后来发现只有金额在(-100000.66,1000000.66)区间中才能真实的储存对应的值,测试了一下代码如下:
    小数点后第二位6开始进位,例如100000.66成为100000.7

1private sub button1_click()sub button1_click(byval sender as system.object, byval e as system.eventargs) handles button1.click
2        dim a as single
3        a = textbox1.text
4 label1.text = a
5    end sub

改成double:
测试成功

1    private sub button1_click()sub button1_click(byval sender as system.object, byval e as system.eventargs) handles button1.click
2        dim a as double
3        a = textbox1.text
4 label1.text = a
5    end sub

所以金额的类型要设为double,咳咳.
