Sqrt The Square root function. This function simply computes the square root of the input value. Note that the square root function is not defined for negative numbers. However, if you try to calculate the square root of a negative number, you do not get any error message. Instead DynRisk simply uses zero as the result value of the edge function. Default parameter values: None Example: Input = 25.0 => Output = 5.0 Input = 64.0 => Output = 8.0 Input = -4.0 => Output = 0
