What will you do to treat the constant 3.14 as a long double?

 [A]. use 3.14LD [B]. use 3.14L [C]. use 3.14DL [D]. use 3.14LF

Explanation:

Given 3.14 is a double constant.

To specify 3.14 as long double, we have to add L to the 3.14. (i.e 3.14L)

 Ashish said: (Dec 3, 2010) For the long double Lf is used as suffix then how L is used?

 Aparna said: (Mar 2, 2011) @Ashish No its totaly wrong. For long double 'L' is used as suffix.

 Mohanraj said: (May 21, 2011) Please explain how 3.14 is treat as double?

 Chaitanya said: (Aug 4, 2011) long double: %LF or %Lf double :%lf float:%f or %e or %g int :%i or %d long int:%ld or %li unsigned long:%lu unsigned int:%u

 Pavan said: (Nov 3, 2011) What exactly difference between double & long double & int?

 Harshareddy said: (Jan 3, 2012) The double is used for floating 44.45, int for integers like 2,567etc , long double for large floating values like 6.98765342 .

 Rajesh said: (Jan 27, 2012) For the long double LF is used in c.

 Sri Ram said: (Sep 1, 2012) Double is also like floating point but having size of 4 bytes,double has 8 bytes,long double has 10 bytes and integer has 2 bytes.So long double can store larger floating points also.Here 3.14 is a long double.

 Rathi said: (Aug 12, 2013) A floating-point constant without an f, F, l, or L suffix has type double. If the letter f or F is the suffix, the constant has type float. If suffixed by the letter l or L, it has type long double.

 Mahendra Kumar Verma said: (Mar 2, 2014) @Chaitanya. In which book defined all type according to your explanation!

 Madhavi said: (Apr 26, 2015) 3.14 can be just double now why is it long double? Can anyone please explain.

 Gyan said: (Aug 30, 2015) Please briefly explain.
