Floating point formats not linked
Author : grant Post Date : 2005-12-30 18:38 Posts : 117	Hi, I have received an e-mail from a person who is getting the following error : "floating point formats not linked Abnormal program termination" while trying to enter text using scanf and the Turbo C compiler. The line of code causing the problem is : scanf("%f",&(emp[0].basic)); The emp array is declared as follows : employee emp[3]; and the struct is defined as follows : typedef struct { char ecode[5],name[10]; float basic,hra,net; }employee; If anyone has experienced a similar problem, could they please post their thoughts here. Regards, Grant

Borland's compilers try to be smart and not link in the floating- point (f-p) library unless you need it. Alas, they all get the decision wrong. One common case is where you don't call any f-p functions, but you have %f or other f-p formats in scanf() or printf() calls. The cure is to call an f-p function, or at least force one to be present in the link. To do that, define this function somewhere in a source file but don't call it: static void forcefloat(float p) { float f = p; forcefloat(&f); } It doesn't have to be in the module with the main program, as long as it's in a module that will be included in the link.
