Check this out: It looks as if this form, y=1.0x + c, is equivalent to 2^n

Does not even need an actual "x":
*******
clear
set obs 10
gen y = 1.2x+3
*******
It does, however, need an addition afterwards.
I guess Kieran`s guess re hexadecimal was right...

But then it seems to take 12 and multiply by 6 to get 72. This is the kind
of arithmetic my students sometimes do... :-)

When I do this, y = 72 for all cases. So 1.2x must be getting
interpreted as 1.2 * 10 = 12. I don't know why, but just follow
Martin's advice and make it
gen y = 1.2*x + 6
Maybe this is a "feature" but if so it doesn't seem like a good one,
since this could be an easy mistake to make.
