Scientif calculator Function 10^x

'x' is the number which 10 needs to be raised to the power of.

So, if 'x' is 2, the result will be 10^2 = 100.

If you're writing a calculator program, then I imagine the user will enter the value of 'x' in a textbox and then press the 10^x button to see the result displayed, either in the same or a different textbox.

If it's the same textbox, then you'd need code like this:

private void btnPower10_Click(object sender, EventArgs e)
{
    double x;

    if(!double.TryParse(textBox1.Text, out x))
    {
        MessageBox.Show("Textbox doesn't contain a valid number. Please amend.");
        textBox1.Focus();
        return;
    }

    double result = Math.Pow(10, x);
    textBox1.Text = result.ToString();
}
