Floating Point And Integer Operation

I was reading a readme file on ticalc for a program that draws the mandelbrot set. It said that it uses integer operation and not floating point. Does anybody know the difference, apparently I'm not smart enough and I'm too lazy to spend time on figuring it out on my own.

Floating point: 5.4
Integer: 5

?

EDIT: I don't know what exactly floating-point is, I think I once did, but probably not Laughing

floating-point means the decimal is not fixed
ex:
fp: 5
fixed(4): 5.0000

fp: 5.56
fixed(1): 5.5

integer is npthing more than fix(0) i assume cuz that removes the fractional part

no, he has to use decimal points because it's the mandelbrot set. In other words, none of it's points that are graphed are greater than two. So, there are many many decimal points. Maybe I'll email the guy. I hope he still uses the same address.

I know how he does that, the integer values don't actually represent the actual coordinates of the pixels, I'll illustrate with some code:

-2->A
2->B
A->Xmin
A->Ymin
B->Xmax
B->Ymax
B-A->E //range

randInt(1,100->C
randInt(1,100->D

pt-On(A+E/C,A+E/D
