usage

[big]Number [b]VERBOSE[/b]: translates a number into a readable string[/big].
 
[b]Returns[/b]:
- a worded 'verbose' string representation of the number 
 
[b]Note[/b]:
- this ignores any decimals
- any number 1 quadrillion or more resolves to "a lot of", see example 3 ;)
 
[b]Application[/b]:
- need to fill out any checks?
- can also be nice for debugging when dealing with large numbers and you find it difficult to
tell right off exactly how big your number is
 
[b]Update[/b]:
- fixed bug in not recognizing 10's
