--- Comment #16 from b. <[email protected]> ---
brainstorming:  
- it's not likely that IEEE 754 will change 'normalized' handling for binary
datatypes,  
- it's not likely that Excel, and following suit Calc, will switch to another
math engine,  
- IEEE provides 'decimals saving' for the decimalxxx datatypes, it comes with
it's own set of issues and isn't yet well matured,  
- you can get them in 'gnumeric', as experimental, but AFAIK they stripped
trailing zero conservation,  
- if ... it's really relevant to you there already is an option, enter your
input as string, e.g. '0.200 with! the leading apostrophe, you can format that
right aligned then looking like a number, and Calc will convert it to 'value'
and happily calculate with it when addressed in formulas.  
- be aware to check for evtl. traps / unexpected behaviour, e.g. low level
supporters analysing sheets from others and identifying 'text' by 'left
aligned' will like to fail.  
- be aware that the workaround provides 'input conservation', but no effect on
calculation results,  
- which IEEE 754 decimals try to provide, with very questionable results, e.g.
adding 0.200 ( relatively imprecise ) and 0.10000000000 ( higher precision )
results in 0.30000000000, faking a precision which is not! provided by the
first operand ( but faking is fashionable since Trump? ).  

Think we can close this report if the OP is satisfied with the workaround.
