Question 1:
exp(x) - 1
=
X
Consider the function f(x)
We shall assume that the function exp(.) is
computed exactly and then rounded to the nearest floating-point number. Using decimal
floating-point arithmetic with six significant digits, evaluate f(0.002). Then, compute the
relative error in the result and explain why the error is so large compared to the precision
used.
