如何将答案转换为两位小数 [英] How to convert answer into two decimal point

问题描述

这是我的代码，我想要的输出是 txtA.Text 和 txtB.Text保留两位小数.

This is my code and I want the output which is txtA.Text and txtB.Text to be in two decimal places.

Public Class Form1
    Private Sub btncalc_Click(ByVal sender As System.Object,
                              ByVal e As System.EventArgs) Handles btncalc.Click
      txtA.Text = Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)
      txtB.Text = Val(txtA.Text) * 1000 / Val(txtG.Text)
    End Sub
End Class

推荐答案

尝试使用 Format 功能:

Private Sub btncalc_Click(ByVal sender As System.Object,
                          ByVal e As System.EventArgs) Handles btncalc.Click
  txtA.Text = Format(Val(txtD.Text) / Val(txtC.Text) * 
                     Val(txtF.Text) / Val(txtE.Text), "0.00")
  txtB.Text = Format(Val(txtA.Text) * 1000 / Val(txtG.Text), "0.00")
End Sub
