Hi, this function can remove some decimals from your floating point number. I just created in 1 minute just in response to some person's question in another community Code: #include<iostream.h> #include<stdio.h> double RemDecimals(double dNum, unsigned int iCant){ int inum = (int)dNum; unsigned int unidades =1; double resnum=dNum; if(inum>9){ unidades++;//porque es de dos cifras ya while((inum/10)>9){//si es mayor a 99 unidades++; inum/=10; } for(unsigned int i=0;i< iCant;i++) dNum*=10; //int cifras = unidades+iCant; int inum2 = (int)dNum; double newnum = (float)inum2; for(unsigned int j=0;j< iCant;j++) newnum/=10; resnum = (float)newnum; } return resnum; } int main(){ double num = 93.161599; printf("num before: %f\n",num); num = RemDecimals(num,2); printf("num after: %f\n",num); cin.get(); return 0; }
