of integer that can be represented is not infinite but is bounded above and below. • The result of the division operation is given as the combination of the quotient and the remainder. Remainder of the result is always truncated. 2. Floating point arithmetic Due to economic consideration‚ computers are designed such that each location in memory at stores only a finite number of digits. For example‚ A computer has a memory in which each location can store one or more

Using AND‚ OR‚ and NOT to Refine your Keyword Search Boolean searching is based on an algebraic system of logic formulated by George Boole‚ a 19th century English mathematician. In a Boolean search‚ keywords are combined by the operators AND‚ OR and NOT to narrow or broaden the search (you do not have to enter them in capitals). AND The operator AND narrows the search by instructing the search engine to search for all the records containing the first keyword‚ then for all the records containing

But in the case of C it is same as s[i]. 3. { main() float me = 1.1; double you = 1.1; if(me==you) printf("I love U"); else printf("I hate U"); } Answer: I hate U Explanation: For floating point numbers (float‚ double‚ long double) the values cannot be predicted exactly. Depending on the number of bytes‚ the precession with of the value represented varies. Float takes 4 bytes and long double takes 10 bytes. So float stores 0.9

The Bouncy Egg Experiment! Mrs. Murosky December 19‚ 2013 Introduction: GOAL: The goal of this experiment is to get an egg to bounce. WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like‚ but allows the experimenter to have fun in the process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine

of ovalbumin‚ the main protein in egg whites. Denaturation is when a protein’s structure is disrupted. Ovalbumin is denatured by heat. In my science class‚ I had learned that heat and pH affect the denaturation of protein. I became curious about how changing the pH would affect the denaturation of ovalbumin when cooking meringue. So I decided to add lemon juice to egg whites and heat the egg whites. The citric acid in the lemon juice would lower the pH of the egg whites. I tried to find the answer

speed should change as you use the pot to vary the voltage on the A/D. 5. Measure the speed of the motor by determining the time between two falling edges of the optical encoder. In your main program display this time on the LCD display. You can use floating point arithmetic to convert this time into RPM. Display the RPM value on the LCD display. What is the maximum motor speed? 6. Measure the speed for several different duty cycles by varying the voltage with the pot.
