I'm getting error for adding TotalCurrent(decimal) adding 0.1 but getting error

I have two methods called IncreaseAmplitude and DecreaseAmplitude of return type float in viewmodel where I'm trying to increment or decrement the TotalCurrent(bind to textbox) by 0.1 but getting error Operator '+' cannot be applied to type decimal and double

private float IncreaseAmplitude()
{
    TotalCurrent = TotalCurrent + 0.1;
}

private float DecreaseAmplitude()
{
    TotalCurrent = TotalCurrent - 0.1;
}

I want pass the methods to delegateCommand so while clicking on those buttons will increment or decrement the value by 0.1 I want to know how to update the textbox and where I'm going wrong?

A textbox contains string and not numbers. To perform math on a string you must parse to a number. – jdweng Mar 18 '23 at 09:48

You need the 0.1 to be the same type as the number you're adding to. Wpf binding will convert between double and string if you bind a double to a textbox textproperty. – Andy Mar 18 '23 at 10:36
@jdweng your suggestion worked – Nehanaaz Shaikh Mar 18 '23 at 10:56
