  1. They have meaning. Integers are understood by ALU. Floats and doubles are understood by FPU. These days FPU is builtin CPU. But in '80 and early '90 in 386 and early 486 FPUs were external chipsets. Coprocessor. Floats are in IEEE 754 standard. https://en.m.wikipedia.org/wiki/IEEE_754 It is much harder to convert float or double to human readable format than plain integer. Therefore there is plentiful parameters which you need to bother about during conversion. Read printf/sprints C/C++ manual %f and %g.

  2. Bit can contains value 0 or 1. If we group 8 bits it is byte. The all other data types have resolution in multiple of byte: 16 bits, 32 bits, 64 bits etc. From computer point of view they are always binary. If typical computer application must print number to user, it has to convert binary to decimal (for non-programmers). It is just on screen. Internally it is is still binary. Conversion takes CPU time and memory. In older times sometimes was used BCD. Now I think it is obsolete. https://en.m.wikipedia.org/wiki/Binary-coded_decimal It could be found in e.g.

  3. I think it's about at what level you wish to describe the theory. It is well understood that, e.g., Maxwell's equations are very simply formulated in a coordinate-free way as, \[dF=0\] \[d*F=j\] But it takes a considerable amount of time to explain to students what all of these symbols mean. Then again, in particularly "dirty" situations, it does no good to tackle the problem in such an all-encompassing, highfalutin way. And we're approaching the level at which everything I say is just my two cents.

  4. But you specified biological sex, so essentially zero is the right answer.
