Question

java代码 转C++

代码很短，多谢！！！

function Trig2(year,month,day) {
n = Math.floor(12.37 * (year -1900 + ((1.0 * month - 0.5)/12.0)));
RAD = 3.14159265/180.0;
t = n / 1236.85;
t2 = t * t;
as = 359.2242 + 29.105356 * n;
am = 306.0253 + 385.816918 * n + 0.010730 * t2;
xtra = 0.75933 + 1.53058868 * n + ((1.178e-4) - (1.55e-7) * t) * t2;
xtra += (0.1734 - 3.93e-4 * t) * Math.sin(RAD * as) - 0.4068 * Math.sin(RAD * am);
i = (xtra > 0.0 ? Math.floor(xtra) : Math.ceil(xtra - 1.0));
j1 = julday(year,month,day);
jd = (2415020 + 28 * n) + i;
return (j1-jd + 30)%30;
}

Answer 1

#include <math.h>
int Trig2(int year, int month, int day){
double n = floor(12.37 * (year -1900 + ((1.0 * month - 0.5) / 12.0)));
double RAD = 3.14159265 / 180.0;
double t = n / 1236.85;
double t2 = t * t;
double as = 359.2242 + 29.105356 * n;
double am = 306.0253 + 385.816918 * n + 0.010730 * t2;
double xtra = 0.75933 + 1.53058868 * n + ((1.178e-4) - (1.55e-7) * t) * t2;
xtra += (0.1734 - 3.93e-4 * t) * sin(RAD * as) - 0.4068 * sin(RAD * am);
double i = (xtra > 0.0 ? floor(xtra) : ceil(xtra - 1.0));
double j1 = julday(year, month, day);
double jd = (2415020 + 28 * n) + i;
return (int)(j1 - jd + 30) % 30;
}
