LC1: Round Off Error (comparing summations in single and double precision)
My Solutions >
Round-off error can often accumulate when performing computations with repeated additions and subtractions. The error accumulates differently depending on the precision with which the numbers are stored. To demonstrate this concept, consider the following summation:
x=5-i=15000000.00001
The analytical result for x is exactly zero, but you will find that x does not equal zero when performing this computation with MATLAB due to the finite precision with which numbers are stored in memory. For this problem, write a script that performs the computation two different ways:
Use all double precision (MATLAB's default numbers) numbers in the calculation. Assign the result for x to the variable named ZeroDouble.
Use all single precision numbers* in the calculation. Assign the result for x using single precision to the variable named ZeroSingle.
"(to create a single precision number, the following can be used single(0.00001
