Hexadecimal display?

This program is supposed to return the lowest number of three inputted double, floating numbers. But it always returns -1.#IND.

Relational operators are evaluated left-to-right. Therefore, a>b>c is equivalent to (a>b) > c, where you compare a boolean (result of a>b) to a double (c). You are unlucky, if that gives an expected answer.

Read about std::min.

This is valid in terms of algebra, but not as c++ code (a>b>c)

You can separate it into two parts, (a>b) (b>c) which must both be true, so combine them with a logical and operator &&.

double smallest (double a, double b, double c){
if (a>b>c)
return c;
if (b>c>a)
return a;
if (c>a>b)
return b;
}

This should be something like this
first make new variable called small;

int small;
//assign a to small;
small = a;

Then start the comparing process

{

if(b<small)
//assign b to small now
small = b;

if(c<small)
small = c;

return small;

}

You can only compare 2 variables in the registor at a time
