Float with more than 3 numbers after the dot.

Question

Hi,

how can i set a float that is able to safe values with up to 8 digits after the dot?

Answer 1

round() can do this, I think.

Answer 2

ok, i will try it.

thank you :)

but i think i have found my Problem: it ist in assigning a float to a constant value of 0.02223 to calculate with it

i'm doing it like this:

float eegum;

.
.
.

if...
eegum = 0.022239;

.
.
.

in the Programm it will Change to "5.07059e+266".

i'm not sure what can cause this problem.
if I work with "cin" it works fine :/

Answer 3

if found the problem! :D

it was a failure in an if-statement without the else. so that the variable "eegum" wasn't set.

and without a default value, it doesn't work properly
