Maximum finite double precision floating-point value.
Include
<float.h>
Value
The value 3.402823e+38.
Remarks
By default, a double type is the same size as a
float type (32-bit representation). The
-fno-short-double switch allows the IEEE 64-bit representation to
be used for a double precision floating-point value.
When building for C99,
the double type is the same size and format as the
float type, and is a 32-bit representation.
