>>7626293>>7626547The winshit calculator can handle up to 32 digit numbers, even 9999...9999, so it's unlikely that it uses the native integers and floats/doubles/long doubles. It might even store shit internally in base ten, in an array, unlike the native integers or floating point numbers.
>>7626275OP, this is purely a software feature, it simply rounds the result up if it's deemed too long. Pic related, the windows XP calculator didn't do this (I've just tried it in a VM, with the longest numbers I could enter).
The floating point shit the others are referring to this is explained in this video
