Is there a round off function in J2ME?

问题

I need roundoff function in J2ME. Math.round() does not seem to exist. Please provide some assistance!

回答1:

Or you can use another approach:

float value;
int base; //base to round

int round_down=(int )((int )(value/base))*base;
int round_up=(int )((int )(value/base+0.5))*base;

回答2:

Math.ceil() or Math.floor() probably but these again are available only for CLDC 1.1 :)
