using loop but have to increment counter with float

how do i get around this?

i have a variable float that i need to use to increment the couther but it throws back error.

is there are another statement i can use to avoid these errors?

for(float i = 0; i<=length; i = i + iterFl)

{

float xmin2tmp = (xminFl * xminFl);// current x2

float xmin3tmp= (xmin2Fl - xmin2tmp);// minimum x2 minus current x2

double y = Math.sqrt(xmin3tmp);// get square root of x2 - x*x

DecimalFormat decFmt =new DecimalFormat();// create object of decimal point

decFmt.setMaximumFractionDigits(1);// set object to allow one decimal place

String output = ("(" + xminFl +", "+ decFmt.format(y) +")");// output (x, y)

xyvalArea.append(output +"\n");// append to textArea with a new line

xminFl = (xminFl + iterFl);

iterFl is giving me the problems
