converting str to int and vice versa

Question

I have a need to convert a string to an int and back after doing some processing. And the string has to be in words like below:

45 - forty five
99 - ninety nine

I searched everywhere for a hint but couldn't find any. I know the obvious switch-case logic but I am curious if theres a more intelligent way doing it with less lines of code.
