numerical constant definition does not work !
... I'm happy with the behaviour of the read statement, the problem is the output of the real_variable = 3.14159265358979 which should give 3.14159265358979 but instead it gives 3.14159274101257 ... ??? -
numerical constant definition does not work !
hello everybody, during an intense programming session I stumbled accross a very strange problem. Have a look at the following simple program: program test implicit none real(kind(1.0d0)), parameter :: real_const = 3.14159265358979 real(kind(1.0d0)) :: real_variable real(kind(1.0d0)) ... -
equivalence of nested do and nested forall
... forall is a fortran 95 statement ... FORALL (i=1:n, j=1:m, a(i,j) /= 0.0 ) a(i,j) = 1.0 / a(i,j) END FORALL ... is equivalent to ... DO i = 1, n DO j = 1,m IF ( a(i,j) /= 0) THEN a(i,j) = 1.0 / a(i,j) ENDIF ENDDO ENDDO ... the order of executing the statements... -
