将Excel公式转换为Java的问题

Question

Hi i am new to java can anyone help me to convert this formula to java code?

=ROUNDUP(POWER(4*B18/PI(),1/3)*100,0)

So far, I have this code:

(((4*variable)/3.142)*0.34)*100;

sorry for asking basic question

Answer 1

In its raw (and ugly) form, it should be something like this:

static double yourFormula(double b18) {
    return Math.ceil(Math.pow(4.0 * b18 / Math.PI, 1.0/3) * 100.0);
}

EDIT: As noted by @Teepeemm, Math#cbrt already calculates the cube root of a number. So the formula should be

static double yourFormula(double b18) {
    return Math.ceil(Math.cbrt(4.0 * b18 / Math.PI) * 100.0);
}

Answer 2

double multiplies =8 * 4;
System.out.println(Math.floor(Math.pow( multiplies/ Math.PI, 1.0/3)*100.0));

double multiplies =8 * 4;
System.out.println(Math.ceil(Math.pow( multiplies/ Math.PI, 1.0/3)*100.0));

double multiplies =8 * 4;
System.out.println(Math.round(Math.pow( multiplies/ Math.PI, 1.0/3)*100.0));

depending on your usage you can use this three methods
