I need to work with bad numbers like this 34564563645560.06005000004<wbr />00001<br />
i read in the delphi help that the extended type allows for 20 siginificant digits.<br />
What is meant by significant digits ?is it the float part of the number or the number all digits including the integer part?<br />
thanks
