Test Status Code Input and Output
1   Pass
a = 1; n = 1; f_correct = a*exp(n); assert(abs(approx_e(a,n)-f_correct)<.001)

f = 2.7181

2   Pass
a = 2^18; n = 0; f_correct = a*exp(n); assert(abs(approx_e(a,n)-f_correct)<.001)

f = 262144

3   Fail
a = pi; n = pi; f_correct = a*exp(n); assert(abs(approx_e(a,n)-f_correct)<.001)

f = 72.6628

Assertion failed.

4   Fail
a = -exp(1); n = exp(2); f_correct = a*exp(n); assert(abs(approx_e(a,n)-f_correct)<.001)
