Double variable precision
Hi xwb, That really helped! Some functions which accept only double variables generated errors, but I used the dble() function to do the type cast. One more question, are you familiar with the LAPACK library routines ? Thanks, Arun -
Double variable precision
Hi xwb, real(kind=10) gives me a size of 16 bytes. Is there a similar way of increasing the precision of 'double precision' variables ? Thanks, Arun -
Double variable precision
Thank you very much for your effort. That answers my question. I will try it out and let you know. Thanks again, Arun -

Double variable precision
Hi xwb, I still am receiving this error: gfortran -ffree-form test1.f95 test1.f95:4.11: real(kind=3) r16 1 Error: Kind 3 not supported for type REAL at (1) Thanks, Arun -
Double variable precision
Hello xwb, I get an error message again: node22/geology> gfortran -ffree-form test1.f test1.f:4.12: real(kind=16) r16 1 Error: Kind 16 not supported for type REAL at (1) Thanks for looking on to this, Arun -
Double variable precision
Hi xwb, Thanks for your continuous help. I tried compiling your test program and I got an error at first: test.f:3.7: real*16 r16 1 Error: Old-style type declaration REAL*16 not supported at (1) And the command I used was: gfortran -ffree-form test.f Then I modified the declaration... -
Double variable precision
Thanks for the reply, xwb. I am a bit more clear about the things. I think I am using Fortran 2003, on Debian Linux. But am not sure, so I am copying in the version dump below. Hope this gives you the info you asked for: node22/geology> gfortran -v Using built-in specs. Target... -
Double variable precision
Hi , I am a beginner and I am trying to help a professor, to execute his Fortran program. He wants to setup the size of DOUBLE variables to 128 bits during compile time. I came across this option to set double variables default precision to 64 bits (-fdefault-double-8). Is there any other...
