Power ^ syntax error

[devjet]

Hello,
what is wrong with this code? it throws a syntax error even if I use power Error line is DA=

Sub btnCalc_Click

Dim Temp As Int
Dim DA As Int
Dim T_S As Double
Dim T_act_K As Double

T_S = 273.15-(0.0019812*edtPA.Text -15)

If rdoTF = 1 Then
T_act_K = (273.15+((edtTemp.Text + 40) / 9 * 5) -40)      ' using F°
Else
T_act_K = (273.15 + edtTemp.Text)                      ' using C°
End If

DA = edtPA.Text + (T_S/0.0019812) * (1-(T_S / T_act_K) ^ 0.2349690)      

End Sub

You should use this equation:

 DA = edtPA.Text +(T_S/0.0019812) * (1- Power((T_S / T_act_K), 0.2349690))

Unfortunately ^ doesn't exist in B4A, it is replaced by Power(Base As Double, Exponent As Double).

Best regards.

I came across this yesterday. I know it's probably not basic-esque, but including stuff like ^, +=, -= etc in the language/IDE would save some skin cells.

+= -= ++ -- ^ :sign0060:
