I know this may seem too simple of a question but I'm having difficulty wrapping my head around the meaning/implication of double
& long
. All online resources are giving official definitions. I'm looking for a layman's explanation.
In Short, my question is: What is the difference between a long long
, a long double
& a long float
?
I tried running a quick test (screenshot attached) to see the byte size of each type, but couldn't make sense out of it. How is a long double
same size as a double
?
long long
is integer (possibly with more range than long
)
long double
is floating point (possibly with more range/precision than double
)
long float
does not exist.
The integer types sorted by range are
_Bool
char
or signed char
or unsigned char
short
(or short int
) or short unsigned
int
or unsigned
long
(or long int
) or long unsigned
long long
(or long long int
) or long long unsigned
The floating-point types sorted by range/precision are
float
double
long double
