/***
|
|
* double StrToDbl(const char *str, char **strStop) - convert string to double
|
|
*
|
|
* Purpose:
|
|
* To convert a string into a double. This function supports
|
|
* simple double representations like '1.234', '.5678'. It also support
|
|
* the a killobyte computaion by appending 'k' to the end of the string
|
|
* as in '1.5k' or '.5k'. The results would then become 1536 and 512.5.
|
|
*
|
|
* Return:
|
|
* The double representation of the string.
|
|
* strStop points to the character that caused the scan to stop.
