The code above gives the result -4.9999999999883

But the code below gives the result -499999.99999883




The pattern ##0.## do not have any 'E' but still it is able find out the exponential representation when an 'E' is used , but it can not find the exponential representation when a 'e' is used.

but the code below works fine with both 'E' & 'e'


Do you have an explanation ?.
