Fortran 9095 Programming Manual Fortran 9095 Programming Manual Brief History of Fortran integer i or in Fortran 90 format: integer: : i Named constants must be declared with the parameter attribute: real, parameter: : pi 3.
Variables In Fortran 90, the best approach is use intrinsic functions to specify the precision you need this guarantees both portability and that you get the precision that you need. Fortran 90 defines about 100 intrinsic functions and a few intrinsic subroutines. Many of these functions can be used for arrays, e. g. for reduction ( SUM ), construct (SPREAD), manipulation ( TRANSPOSE ). Fortran Reference Guide Version 2018 vi.

Previous: Contents: Index. Explicitly declare the length of an INTEGER by using a kind parameter, such as INTEGER (KIND8). DIGITAL Fortran 90 provides intrinsic INTEGER kinds of 1, 2, 4, and 8. Each INTEGER kind number corresponds to number of bytes used by that intrinsic representation.
