|Anyone explain this?|
|Kiran Chowdary said: (Apr 14, 2011)|
|Can any one explain please?|
|Jitendra Jain said: (Apr 30, 2011)|
|I explain it that it is a consatant and fixed size.|
|Suganya said: (Sep 2, 2011)|
|Please give a more explanation?|
|Kirti said: (Oct 12, 2011)|
|1.7E +/- 308 (15 digits) this answer is correct.|

|What is significance of 4932?|
|Pawan said: (Feb 5, 2012)|
|According to "Let us C" it is -1.7e4932 to 1.7e4932.
So please tell me which one is correct?
|Sundar said: (Dec 2, 2012)|
|long double (80 bits or 10 bytes) : 3.4 * (10^-4932) to 1.1 * (10^+4932)
In Turbo C: (16 bit DOS Operating system).
printf("long double size = %d", sizeof(long double));
If you execute the same in IndiaBIX's Online compiler (32 bit Linux OS), the output will be 12.

Yes friend you are absolutely correct but in books long double range is given as -1.7e4932 to +1.7e4932 and of the size of 10 bytes with format specifier as %Lf.

|If the OS different means the range of the datatype is also different?|
|Parag said: (Mar 8, 2015)|
|I too think that it is -1.7e4932 to +1.7e4932.|
|Ishaan said: (Dec 28, 2015)|
|Can someone explain how it comes 80 bits?
Is their any logic to find the value?
Long means 4 bytes.
Double means 8 bytes.
How long double 10 bytes?
|Purni said: (Mar 5, 2016)|
|The long double default range is same as the the double from 1.7E-308 to 1.7E+308.
But the long double data type is system(Processor, ABI, compiler)dependent and so its range varies accordingly.
You can also check the long double range with the function std::numeric_limits<long double>::min and std::numeric_limits<long double>::max.

|What is E stands for?|
|Nakul said: (May 31, 2017)|
|Can anyone explain it properly?|
|Shivam said: (Feb 10, 2021)|
|I think. -1.7e4932 is the right answer.|
