lg符号怎么编译的，怎样才能弄正确？电脑显示D:\Microsoft Visual Studio\MyProjects\算数\1.cpp(5) : error
#include <stdio.h>int main()
{
float d=300000,p=6000,r=0.01,m;
m=lg10(p/(p-d*r))/lg10(1+r);
printf("m=%6.1f\n",m);
return 0;
}
程序代码：#include <stdio.h>
#include <math.h>
int main()
{
float d=300000,p=6000,r=0.01,m;
m=log(p/(p-d*r))/log(1+r);
printf("m=%6.1f\n",m);
return 0;
}
