Since the Windows console has poor UTF-8 support, there are problems with a couple of the characters ( and ) that quadraticpy uses We have provided quadratic_unipy which displays the correct symbols on Linux and Mac OS X, and alternatives (^2 and ->) on WindowsMake Barcode In .NET FrameworkUsing Barcode printer for ASP.NET Control to generate, create barcode image in ASP.NET applications.except ValueError as err: print(err) return x Code128 Maker In Visual C#Using Barcode maker for Visual Studio .NET Control to generate, create Code 128A image in .NET framework applications. 2 Data Types Barcode Drawer In C#Using Barcode maker for .NET Control to generate, create bar code image in Visual Studio .NET applications.This function will loop until the user enters a valid oating-point number (such as 05, -9, 21, 492), and will accept 0 only if allow_zero is True Once the get_float() function is de ned, the rest of the code is executed We ll look at it in three parts, starting with the user interaction:EAN-13 Supplement 5 Encoder In .NETUsing Barcode creator for Visual Studio .NET Control to generate, create European Article Number 13 image in VS .NET applications.print("ax\N{SUPERSCRIPT a = get_float("enter a: b = get_float("enter b: c = get_float("enter c: TWO} + bx + c = 0") ", False) ", True) ", True)Code39 Creation In C#.NETUsing Barcode creator for Visual Studio .NET Control to generate, create USS Code 39 image in VS .NET applications.Thanks to the get_float() function, getting the a, b, and c factors is simple The Boolean second argument says whether 0 is acceptablex1 = None x2 = None discriminant = (b ** 2) - (4 * a * c) if discriminant == 0: x1 = -(b / (2 * a)) else: if discriminant > 0: root = mathsqrt(discriminant) else: # discriminant < 0 root = cmathsqrt(discriminant) x1 = (-b + root) / (2 * a) x2 = (-b - root) / (2 * a)The code looks a bit different to the formula because we begin by calculating the discriminant If the discriminant is 0, we know that we have one real solution and so we calculate it directly Otherwise, we take the real or complex square root of the discriminant and calculate the two rootsequation = ("{0}x\N{SUPERSCRIPT TWO} + {1}x + {2} = 0" " \N{RIGHTWARDS ARROW} x = {3}")format(a, b, c, x1) if x2 is not None: equation += " or x = {0}"format(x2) print(equation)We haven t done any fancy formatting since Python s defaults for oating-point numbers are ne for this example, but we have used Unicode character names for a couple of special characters
