這篇文章主要介紹了C語言實現(xiàn)直角坐標轉換為極坐標的方法,涉及C語言進行三角函數(shù)與數(shù)值運算相關操作技巧,需要的朋友可以參考下
本文實例講述了C語言實現(xiàn)直角坐標轉換為極坐標的方法。分享給大家供大家參考,具體如下:
#include<stdio.h> #include<math.h> struct complex_s{ double x,y; }; double real_part(struct complex_s z){ return z.x; } double img_part(struct complex_s z){ return z.y; } double magnitude(struct complex_s z){ return sqrt(z.x*z.x + z.y*z.y); } double angle(struct complex_s z){ return atan2(z.y, z.x); } struct complex_s make_from_real_img(double x, double y){ struct complex_s z; z.x = x; z.y = y; return z; } struct complex_s make_from_mag_ang(double r, double A){ struct complex_s z; z.x = r * cos(A); z.y = r * sin(A); return z; } struct complex_s add_complex(struct complex_s z1,struct complex_s z2){ return make_from_real_img(real_part(z1)+real_part(z2), img_part(z1) + img_part(z2)); } struct complex_s sub_complex(struct complex_s z1,struct complex_s z2){ return make_from_real_img(real_part(z1)-real_part(z2), img_part(z1) - img_part(z2)); } struct complex_s mul_complex(struct complex_s z1,struct complex_s z2){ return make_from_mag_ang(real_part(z1)*real_part(z2), img_part(z1) + img_part(z2)); } struct complex_s div_complex(struct complex_s z1,struct complex_s z2){ return make_from_mag_ang(real_part(z1)/real_part(z2), img_part(z1) + img_part(z2)); } int main(void){ struct complex_s z1 = {3.0,4.0}; struct complex_s z2= {2.0,5.0}; struct complex_s x; x = add_complex(z1,z2); printf("x={%f,%f}",x.x,x.y); return 0; }
結果:
[root@localhost struct]# ./jizuobiao.out x={5.000000,9.000000}
希望本文所述對大家C語言程序設計有所幫助。
