While porting project from 64bit to 32 bit : float changed to long double gives error for %f

As while porting 64 bit project to 32 bit project for making range compatible changed:

typedef float float_t;

to

typedef long double float_t;

All goes perfect but error is coming in all printf specifier for %f. I don't want to change to %Le in whole code.

Please suggest any generic solution so it is campatible to both 32 bit and 64 bit system in c language.

You did not sepcify what language you are using. In C++ std::cout is preferred over printf and it will give you type-correct formatting.

If you are using C, you could define a macro based on the platform for both the type of the floating point variables and the formatting string for printf

You are going to have to use a #define for the format string for the float / long double, or use a special formatting function
