vb.net中科学计算器中的数学函数 [英] mathematic function in scientific calculator in vb.net

问题描述

hai，我想知道在vb.net中操作Sin，Tan，Cos，Log，m +，mr和mc的代码是什么.此功能将添加到我的项目科学计算器中.目前，我正在创建科学计算器项目.这是我的项目，希望可以为您提供参考.

私人Sub btnsum_Click(ByVal发送者为System.Object，ByVal e为System.EventArgs)处理btnsum.Click
昏暗结果为整数
total2 = Val(answer.Text)
选择案例[操作员]
案例"+"
结果= total1 + total2
answer.Text =结果
案例-"
结果=总数1-总数2
answer.Text =结果
案例"/"
结果=总1/总2
answer.Text =结果
案例"*"
结果= total1 * total2
answer.Text =结果
结束选择
answer.Text =结果
结束Sub

hai, i want to know what is code for operation Sin, Tan , Cos , Log, m+, mr and mc in vb.net. This function will added into my project scientific calculator.Currently i am create scientific calculator project. Here is my project which i hope as your reference.

Private Sub btnsum_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsum.Click
Dim result As Integer
total2 = Val(answer.Text)
Select Case [Operator]
Case "+"
result = total1 + total2
answer.Text = result
Case "-"
result = total1 - total2
answer.Text = result
Case "/"
result = total1 / total2
answer.Text = result
Case "*"
result = total1 * total2
answer.Text = result
End Select
answer.Text = result
End Sub
