Computational Domain

• Range of numbers (from /usr/include/limits.h):

• FLT_DIG 6 /* decimal digits of precision of a float */

• FLT_MAX 3.40282347E+38F

• FLT_MIN 1.17549435E-38F

• DBL_DIG 15 /* decimal digits of precision of a double */

• DBL_MAX 1.7976931348623157E+308

• DBL_MIN 2.2250738585072014E-308

• LONGLONG_MIN -9223372036854775807LL-1LL

• LONGLONG_MAX 9223372036854775807LL

• ULONGLONG_MAX 18446744073709551615LLU

• The extended precision (REAL*16) is available and supported by the compiler. But this mode of calculation is slow (by factor ~40)
