* Dtoa needs to have a particular environment set up for it so

|

|
|
|
|
|
*
|
|
|
|
|
* The way it works is that when you link with it, its definitions
|
|
|
|
|
* of dtoa, strtod etc. override the default ones. So if you fail
|
|
|
|
|
* to link with this library everything will still work, it's just
|
|
|
|
|
* subtly wrong.
