I am a beginner learning about MATLAB scientific computation, floating point numbers, and numerical error. When I am using a very small $x$ value for some equations, such as $y(x) = (\exp(x)-1-x)/x^2$, the relative error could get very large. To overcome this, I am told to use the built in vpa function for better precision. Are there any other ways to increase precision without vpa?

Are there any ways to increase the precision in MATLAB without built in functions?
