+===== Using floating-point variables =====
+It is sometimes necessary in AVR programs to use floating-point variables. For calculating with them and presenting with //printf//-type functions, the following changes are necessary in the configuration of the project:
+**1.** Open the configuration of the project from the menu //File → Properties//. On the leftside panel open //AVR C Linker → Libraries//, where in addition to HomeLab library other library objects must be included //printf_flt// and //m// (libprintf_flt.a ja libm.a).
+**2.** Then open //AVR C Linker → General// and into box of //Other Arguments// add line //-uvfprintf//.
