Sorry, in next version. We will use long double in all operation instead of double to avoid all precision error.

More decimal places

The iPhone calculator and other iPad calculators allow more decimal places to display. Could you please address this for calculator 4? For example, typing ".0004 =" displays as 4e-5. This makes math with small numbers impossible. I like the way calculator 4 looks and behaves, but this flaw makes it unusable for me. I suggest a slightly smaller number display to accommodate a precision of at least 10 digits before resorting to exponent notation.

Thousand separator

Coul you add a Setting ítem that enable a point (.) as thousand separator. European users (not english) uses this notation: one thousand twenty four comma thirty five is 1.024,35

Delete last digit

Could you add the swipe gesture to delete the last symbol, like it is done for the original iPhone calc? So that you swipe left on the calc "monitor" and it erase the last digit. That would be handy when you mistype the number.
