What are the features of Fortran 95?

What is the latest version of Fortran?

The latest standard is Fortran 95. Fortran 95 contains only minor changes to Fortran 90; however, a few of the obsolescent features identified in Fortran 90 were deleted. Because of the requirement that all of FORTRAN 77’s features must be contained in Fortran 90, there are often several ways to do the same thing, which may lead to confusion.

Why is the do…while syntax not used in Fortran?

Since the DO…WHILE syntax does not enable Fortran to do anything it could not otherwise do, some authorities disapprove of its use. Note that DO loops, like IF and CASE constructs, may be named.

Can sign be negative in Fortran 95?

74 INTRINSIC PROCEDURES If the second argument of SIGNis a variable or expression of zero value, the value of SIGNmay be positive or negative. This facility is provided in Fortran 95 because some processors, following an IEEE standard, have one bit pattern for positive zero and another for negative zero. 5.4 Numeric inquiry functions
