float pi = Math.PIF. That doesn't work. The only way I was able to have a working class using floats, I had to initialize pi as follows just out of curiousity, since i'm taking a java class now. why would you want to change math.pi into a float? edit: don't have a working copy of the java ide yet but, have you...

Answer = 81. In this program, base and exponent are assigned values 3 and 4 respectively. Using the while loop, we keep on multiplying the result by base until the exponent becomes zero. In this case, we multiply result by base 4 times in total, so result = 1 * 3 * 3 * 3 * 3 = 81.

1Jun 09, 2012 · The Raspberry header is the key to its ability to interface with the real world. The Pi either uses a 40-pin or 26-pin depending on the model and it is important to understand how those pins are arranged and labelled. Because less "juggling" is required to accommodate this repetition, Java's sin(), cos() and tan() functions have "fast cases" for input values between -pi/2 and pi/2. Approximate number of clock cycles (i.e. relative to the "best case" for a floating point addition on many processors) are approximately as follows: Which line from the excerpt expresses a subjective viewpoint by the author_Calculating pi to an arbitrary number of digits Here is a really usefull helper class that you can use to calculate PI to an arbitrary number of (string) digits: sourcecode download . Note that you do need the JDK 1.5 for it. In the next Java line, We are calculating the volume of a Cylinder. Volume = Math.PI * radius * radius * height; In the next line, We are calculating the Lateral Surface Area of a Cylinder and Top Or Bottom Surface Area of a Cylinder.
