Feet/Feet-Inch-Fraction Conversions (compact format)

[Albert Chan]

It would be nice if both FTFI and FIFT can be combined as one, say feet()

Float 6.111 is very hard to know its meaning. 6.111 ft ? 6 ft 11 in 10/16 ?

I propose use imaginary number to signal the difference, a signal for multiple units (ft, in, 16th)

6 + 1110 i = 6 ft 11 in 10/16
6.111 = 6.111 ft

Example: what is 5.78125 ft + (6 ft 11 in 10/16) ?

feet(5.78125 + 6 + 1110 i) => 12.75 ft
feet(12.75) => 12 + 900 i (12 ft 9 in)
