Math.round in J2me

[shirodas]

Hi,

In j2me it does not support math as i want to implement this codes it came out error

public void setFrameRate(float fps) {
if (fps != 0f) {
delay = Math.round(100f / fps);
}
}

I google in and found soulution out a Java floating point emulation library for MIDP devices , with that i am able to use the Math in j2me?

If not any suggestion for me to solve that error?

Thank in advance =)

Hi i found the solution, but by using MathSupport.round() will it be the same as Math.round() ?

Hi shirodas,

to have rounding in Java ME you have two choices:

* use one of the available APIs (like the one you're probably mentioning in your second post): MicroFloat is one of these

* implement it by your own (you can find many available code samples around, like this)

Hope it helps,

Round in Java ME, e.g. in J2ME

The code below is example, method that shows how to
round a double to n decimals:

private double round(double num,int numDecim){
long p=1;
//next line – calculate pow(10,numDecim)
for(int i=0;i<numDecim;i++)p*=10;

return (double)(int)(p*num+0.5)/p;
}
You may use double p=1.0; or p*=10.0; instead.

There are different solutions, bat I hope this can help.
