Imperial feet-inches, if you want to format proper number fraction part, the denominator like /2, /4, /8, /16, /32, /64, /128, /256, /512, etc. use MROUND() with TEXT() functions.
MROUND() round the number to the desired multiple, for example 1/64, and Excel TEXT() format will take care the rest.
The denominator format number of digits (##) should be equal or more than the multiple (64)
TEXT(MROUND(A2, 1/64),"# #/##")
My thoughts on using INT() function in formula to convert to, or from any unit and depending the case of usage, it is good with positive number greater 0, but not with negative number less than 0, INT() is not symmetrical when rounding, I would avoid it all cost!
Ex:
INT(9.8) = 9
INT(-9.8) = -10
As you can see, INT() rounds a number down to the nearest integer, therefor when it in formula for conversion it behaves different with negative number!
Sum up, INT() when use in formula to compute a positive number, like convert to 'feet-inches', it's OK, but beware when using with negative number like minus tolerance it's may be incorrect result!
My 2 cents,
