Calculator Calculation_Calculator Calculation import gnuradio.input.Calculator gnuradio.input.Calculator.Calculator($num_inputs) self.$(id).set_parameters($Exp,$num_inputs) Expression Exp string Num inputs num_inputs 1 int in0 float $num_inputs out float Variable names must be a0,a1,a2 and so on. You can use maximum 10 variables per block. Example to add 5 variables: "a0+a1+a2+a3+a4" To perform Exponential(power) calculations on operators use the following: a0**a1 To perform calculations like sqrt, log or exp use the following: sqrt(a4) log(a2) exp(a8)
