# calc: calculations: code: 'assume' integers or 'clearly identifyable'?

fresh new year to all, may it be better than the last ...

'integers' are guesses? or clearly identifiable in IEEE 754 doubles,

i had some discussions about floats and doubles lately and thought about 'improving' the calculation and rounding errors of them, the distinction between 'integers' and 'fractions' is important for that (values where - decimally - other digits than '0' appear after the decimal point, or not), and i vaguely remember that @erAck had written somewhere 'assumed to be integers' or something like that ... but couldn't find the place right away ...

my question - it's more a question for developers - is

what is the decision in the calculation routines 'integer' or 'fraction'? or is it not clearly visible in the bit-salad?

thanks for any help, it won't directly solve problems of other users but could help to improve calc and IEEE 754 massively ... if ... i'm right with my guessing ...
