when i compile the following code about function overloading the compiler throws the error message:
" ambiguity between 'abso(int)' and 'abso(float)' "

#include<iostream.h>
#include<conio.h>
int abso(int i);
long abso(long l);
float abso(float f);
main()
{
clrscr();
abso(-10);
abso(19L);
abso(0.5);
getch();
}

int abso(int i)
{
cout <<"IN INT ABSO FUNCTION--";
cout << i ;
}
float abso(float f)
{
cout <<"IN FLOAT FUNCTION";
cout << f;
}
long abso(long l)
{
cout <<"IN LONG FUNCTION--";
cout << l;
}

but the program compiles and runs well if i remove the float part and overload int and long only...why wont the compiler overload when i int and float together?

i use the borland turboC++ compiler... can u plz explain why this is happening?
