你的ab,bc,cd,da定义为实型 运算y=sqrt（x）的时候x是整型 y也变成整型 所以要强制类型转换哦 在前面加个float即可 如：y=（float）sqrt（x）include<math.h> main(){ int oa,ob,oc,od,ac,bd;float ab,bc,cd,da;scanf("%d,%d,%d,%d",&oa,&ob,&oc,&od);ab=(float)sqrt(o...
数学函数异常:log: DOMAIN error 这是cmath 或 math.h 里面的数学函数无法正常计算引起的,例如 domain error 定义域错误,就是函数的参数值超过了函数能够处理的范围,例如 log 函数无法计算 0 和负数的对数值,计算 log(-1.0) 的值就会弹出前面截图的对话框。 如果程序里面有大量的计算,不可能每一个函数计算的时...
fortran知识 | 代码错误(domain error) 如图所示,提示为:domain error 这表示数学函数错误,如超出数学函数的定义域,负数开平方,分母为0等等;也有可能是浮点数错误,比如sqrt(4),因为4是整型。 该错误属于运行时错误,需要Debug来发现问题所在。
