72 / 2000 = .036, it does not equal .0359999999999999 like the examples
   have implied. .036 * 750 is 27.0, again, not 26.99999999.

In decimal.

In binary, .036 is not representable exactly (that's true of most
"round" decimal values).

This is pretty standard floating point arithmetic stuff.  <insert
obligitory mention of how some of us "cut our teeth" on this stuff
*ahem* many years ago and how they probably don't cover it anymore
