How to get percentage in float 0 to 1 with integer values?

Question

I need to get a float value based on percentage.

For example:

1%: 0.01 10%: 0.10 25%: 0.25 50%: 0.5 And so on.

I've tried getting a 0-100 percent value(Which works) and uploading it to a string:

String value = "0." + percent;

and parsing it as a float:

Float.parseFloat(value);

But that doesn't work. Any help is appreciated, thanks!

Your question is not clear. Are you asking how to display a number between 0 and 1 in binary? — Eran, Oct 23 '14 at 12:39
Absolutely no idea what you want to achieve. What do you mean with "0-1 percentage"? And why is 5 out of 10 0.1?! — Uwe Allner, Oct 23 '14 at 12:44

float percentage = (float)intPersentValue/100.0f; this will give floating value like 25 to 0.25

I did not actually get the question but are you trying to get

0.1 => 1.0 
0.015 => 0.1

or

0.1  => 100% 
0.01 => 10%

If you want 5/10 => 0.5 you can use:

int a = 5;
int b = 10;
float percentage = (float)a/float(b);

If you can elaborate a bit more I can help.

Well the idea is to set the progress of a View that requires a float 0-1 to the percentage of a cap and number. Basically getting a percentage of 0 to 100 and turning it to a float 0-1 – JediBurrell Oct 23 '14 at 13:03
so you need to use @blackbelt 's answer. `(float) i/ (float)iCap` If we set min = 0.0. – Hakes Oct 23 '14 at 13:07
We removed the min because min is 0.0 already in (x - min) / (max - min). We just added a typecast to float. Without typecase: 10/100 = 0 – Hakes Oct 23 '14 at 13:14
so x/max? Maximum is one so it would stay the same. – JediBurrell Oct 23 '14 at 13:50
Maximum is 100 in you case. – Hakes Oct 23 '14 at 15:05
but no, I need it to be 0-1. I fixed it though, I'll edit what i did in a little later. – JediBurrell Oct 23 '14 at 15:10
