Do need that one, though #include <cfloat> is preferred for C++.
Also need <cstdio> or <stdio.h> for C-style i/o or <iostream> for C++

DBL_MAX for doubles, LDBL_MAX for long doubles.
If you use C-style i/o, be careful about format specifiers for printf()
when printing long doubles (or long anything).
