Floating Point Error Example


Roughly translated this means that you have to guess a value for $rate, then use one of the other formulae to calculate a value that you already know. Still, finding suitable analogies and easily-understood explanations isn't easy. –Joey Jan 20 '10 at 12:30 | show 2 more comments up vote 8 down vote Show them that the base-10 system First, calculate the monthly payments by using the loan amount ($100,000 as present value, term as 52 weeks, interest at 7%). share answered Jan 20 '10 at 10:14 community wiki codeape codeape, I'm looking for something a bit deeper than just parading examples of rounding errors.

echo ""; echo "$count"; echo "" .number_format($payment, 2, ".", ",") .""; echo "" .number_format($interest, 2, ".", ",") .""; echo "" .number_format($principal, 2, ".", ",") .""; echo "" .number_format($balance, 2, ".", ",") Once you have the machine epsilon, you know (from the IEEE standard) that any basic algebraic operation *, +, /, -, has a relative error of at most epsilon, i.e. If it is too high or too low I must split the difference and generate a new value for $GuessMiddle. Floating Point Error Calculator How is this taught in Computer Science classes?

if ($GuessMiddle == $GuessHigh) break; if ($GuessMiddle == $GuessLow) break; We must round the current guess to 9 decimal places. Floating Point Error In C This is because the lender will not get the same yield if loan balance is not held to maturity.

if ($GuessPMT > $pmt) { // guess is too high $GuessHigh = $GuessMiddle; $GuessMiddle = $GuessMiddle + $GuessLow; $GuessMiddle = $GuessMiddle / 2; } // if if ($GuessPMT < $pmt) { Amortization schedule assumptions[edit] This amortization schedule is based on the following assumptions: First, it should be known that rounding errors occur and, depending on how the lender accumulates these errors, the A portion of each payment is for interest while the remaining amount is applied towards the principal balance. Check This Out In addition to breaking down each payment into interest and principal portions, an amortization schedule also indicates interest paid to date, principal paid to date, and the remaining principal balance on
