Round a float to n decimal places.

in Programming Questions • 10 months ago

Hi, I'm displaying some text that I need to round to the nearest second decimal place

For example:

x = 1.000000000000000000000000000000000000000001

y = 1.10000000000000000000000001

a = x + y

roundDecimal(a);

a = 1.10

Is there anyway to do this?

Cheers

Found this one on Stackoverflow website. I am not sure if the result is OS related, because the result is 2,10 (correct for me, but not for Americans).

float x = 1.000000000000000000000000000000000000000001;
float y = 1.10000000000000000000000001;
float a;
print(String.format("%.2f", a=x+y));

v.k.

Processing has nf() and some variations, linked from that page.
