Lazy word problems

Summary
A teacher was told to prepare word problems for the students. She is given a list of equations and told to write them as the corresponding word problem. However, she is very lazy, so she doesn't put much creativity into it. Instead, she simply writes it literally. For example, when she reads 1+1, she writes one plus one, 47 * 2 would turn into forty seven times two, and 56.2 / 7.4 would become fifty six point two divided by seven point four.
Write some code to help this lazy teacher out.
Details
- Numbers may include a decimal point and a negative sign.
- Numbers should be written in the short scale. (i.e.,
1,000,000,000isone billion) - Numbers can go up to 999,999,999,999,999,999 (
nine hundred ninety nine quadrillion...nine hundred ninety nine). - Groups of zeros must be left out. e.g.
1,000,000isone millionnotone million zero thousand zero hundred. - There can be arbitrarily many digits past the decimal point.
- Digits after the decimal point must be listed digit by digit. e.g.
12.34istwelve point three fournottwelve point thirty four. - Two numbers are always separated by an operator.
- The valid operators are plus (
+), minus (-), times (*), and divided by (/). - There are no parentheses.
- Numbers such as
1234may optionally include anandin their output, as inone thousand two hundred *and* thirty four. - Commas and whitespace on the input may be ignored.
Examples
Input: 24 + 65
Output: twenty four plus sixty five
Input: 3.33333 - 0
Output: three point three three three three three minus zero
Input: 3.6 * 18.18 / 999.0
Output: three point six times eighteen point one eight divided by nine hundred ninety nine point zero
Input: 1-1
Output: one minus one
Input: 1+-1
Output: one plus negative one
Input: 1,000,000,000 + 0.2
Output: one billion plus zero point two
Input: 123,000,456,789,012,345.6789
Output: one hundred twenty three quadrillion four hundred fifty six billion seven hundred eighty nine million twelve thousand three hundred forty five point six seven eight nine
Input: -4.3 * 7
Output: negative four point three times seven
Input: -1-1--1
Output: negative one minus one minus negative one
