It could be that it should save more (I'll look into it). However, neither Gnumeric nor FreeCAD are able to represent the result of your computation exactly (18446744073709551616), as it has more significant digits than a double can represent.ulrich1a wrote: FreeCAD does just not save the last digit of the mantissa of a number written into a cell. Adding this one digit in the input-field gives again a zero difference between a Gnumeric result copied into a FreeCAD cell and a FreeCAD calculation.
