Using If and Else with decimal points in printf

#include<'stdio.h'>
main()
{

float sal,tot, inc;

printf("enter your salary : ");
scanf("%f",&sal);

if( sal < 10000 )
{inc=sal*1.345/100;
tot=(sal*101.345)/100; }
else if( sal < 25000 )
{inc=sal*0.75/100;
tot=(sal*100.75)/100; }
else if( sal >=25000 )
{inc=sal*0.456/100;
tot=(sal*100.456)/100; }
printf("\n\n");
printf("Basic Sal : %.2f \n",sal);
printf("Increment : %.3f \n",inc);
printf("Total : %.2f \n",tot);
