七常用測量程序設計

(1)將以度分秒表示的角度轉(zhuǎn)換為以弧度表示的角度。(提示度分秒的格式為：d.mmss,d--代表

度，mm--代表分,ss--代表秒，如20度34分56.12秒的度分秒格式是20.345612)

usingSystem;

usingSystem.Collections.Generic;

usingSystem.Text;

namespaceConsoleApplicationl

classApplication

(

staticvoidMain(string[]a)

Console.Write("請輸入角度[ddd.mmss]=");

try

doubleangle=double.Parse(Console.ReadLine());

doubleradian=DEG(angle);

Console.WriteLine("角度[{0}]的弧度值為[{1}]",angle,radian);

)

catch(Exception)

(

)

)

〃將ddd.mmss轉(zhuǎn)為弧度

staticpublicdoubleDEG(doubleang)

(

intfuhao=1;

if(ang<0)fuhao=-1;

ang=Math.Abs(ang)+1.0E-15;

intd=(int)ang;

intm=((int)(ang*100))-d*100;

doubles=ang*10000-m*100-d*10000;

return((d+m/60.0+s/3600.0)*fuhao)/180.0*Math.PI;

)

}

)

(2)將以弧度表示的角度轉(zhuǎn)換為以度分秒表示的角度。(提示度分秒的格式為：d.mmss,d--代表

度，mm一代表分，ss-代表秒，如20度34分56.12秒的度分秒格式是20.345612)

usingSystem;

usingSystem.Collections.Generic;

usingSystem.Text;

doubleangle=DMS(radian);

Console.WriteLine("角度[{0}]的度分秒值為[{1}]",radian,angle);

)

catch(Exception)

(

)

)

〃將弧度轉(zhuǎn)為ddd.mmss

staticpublicdoubleDMS(doubleang)

(

ang+=1.0E-15;〃加上一個小量，以保證進位

intfuhao=(int)(ang/Math.Abs(ang));

ang=Math.Abs(ang)*180.0/Math.PI;

intd=(int)ang;

ang=(ang-d)*60.0;

R=DEG(R);

Console.WriteLine("指標差={0}垂直度={1}”，DMS((L+R)*0.5-180.0),

DMS((R-L)*0.5-90));

)

catch(Exception)

(

)

)

//將ddd.mmss轉(zhuǎn)為度

staticpublicdoubleDEG(doubleang)

(

intfuhao=1;

if(ang<0)fuhao=-1;

ang=Math.Abs(ang)+1.0E-15;

intd=(int)ang;

intm=((int)(ang*100))-d*100;

doubles=ang*10000-m*100-d*10000;

return((d+m/60.0+s/3600.0)*fuhao)/180.0*Math.PI;

)

〃將度轉(zhuǎn)為ddd.mmss

staticpublicdoubleDMS(doubleang)

ang+=1.0E-15;〃加上一個小量，以保證進位

intfuhao=(int)(ang/Math.Abs(ang));

ang=Math.Abs(ang);

intd=(int)ang;

ang=(ang-d)*60.0;

intm=(int)ang;

doubles=(ang-m)*60.0;

Console.WriteLine("兩角度的和={0}兩角度的差L+R,L-R);

)

catch(Exception)

)

)

class角度
