Number of decimal digits of precision in a double precision float-
ing-point value
<float.h>
6 by default, 15 if the switch -fno-short-double is used
By default, a double type is the same size as a float type (32-bit repre-
sentation). The -fno-short-double switch allows the IEEE 64-bit
representation to be used for a double precision floating-point value.
precision floating-point value
<float.h>
1.192093e-07 by default, 2.220446e-16 if the switch
-fno-short-double is used
By default, a double type is the same size as a float type (32-bit repre-
sentation). The -fno-short-double switch allows the IEEE 64-bit
representation to be used for a double precision floating-point value.
Number of base-FLT_RADIX digits in a double precision floating-point
significand
<float.h>
24 by default, 53 if the switch -fno-short-double is used
By default, a double type is the same size as a float type (32-bit repre-
sentation). The -fno-short-double switch allows the IEEE 64-bit
representation to be used for a double precision floating-point value.
Maximum finite double precision floating-point value
<float.h>
3.402823e+38 by default, 1.797693e+308 if the switch
-fno-short-double is used
By default, a double type is the same size as a float type (32-bit repre-
sentation). The -fno-short-double switch allows the IEEE 64-bit
representation to be used for a double precision floating-point value.
The difference between 1.0 and the next larger representable double
consists of macros that specify various properties of float-
