Returns a string in extended form:.

Snnnnnnnnnnnnnnnnnnnn example: -4318384739357974916

This function uses GetStr() and then "unroll" the trailer exponent adding the required zeroes at the end/begin of the number (for positive/ negative exponents) and the dot.

Note:
This function could take a *lot* of memory for big big numbers (like 123E+10000) and this can mean DoS (Denial Of Service): use with care !!!
