!****p* Program/H5_test_buildiface
!
! NAME
! Executable: H5_test_buildiface
!
! FILE
! fortran/src/H5_test_buildiface.F90
!
! PURPOSE
! This stand alone program is used at build time to generate the program
! H5fortran_detect.f90. It cycles through all the available KIND parameters for
! integers and reals. The appropriate program and subroutines are then generated
! depending on which of the KIND values are found.
!
! NOTES
! This program uses the Fortran 2008 intrinsic function STORAGE_SIZE or SIZEOF
! depending on availability.It generates code that makes use of
! STORAGE_SIZE/SIZEOF in H5fortran_detect.f90. STORAGE_SIZE is standard
! compliant and should always be chosen over SIZEOF.
!
! The availability of STORAGE_SIZE/SIZEOF is checked at configure time and the TRUE/FALSE
! condition is set in the configure variable "FORTRAN_HAVE_STORAGE_SIZE" or
! "FORTRAN_HAVE_SIZEOF".
!
! The use of C_SIZOF(X) is not used since the argument X must be an interoperable
! data entity.

! TEST IF TWO REAL NUMBERS ARE EQUAL
! ***********************************
! [1] The test performed is
!
! ABS( x - y ) < ( ULP * SPACING( MAX(ABS(x),ABS(y)) ) )
!
! The numbers are considered equal if true
!
! The intrinsic function SPACING(x) returns the absolute spacing of numbers
! near the value of x,
!
! { EXPONENT(x)-DIGITS(x)
! { 2.0 for x /= 0
! SPACING(x) = {
! {
! { TINY(x) for x == 0
!
! The ULP optional argument scales the comparison:
!
! Unit of data precision. The acronym stands for "unit in
! the last place," the smallest possible increment or decrement
! that can be made using a machine's floating point arithmetic.
! A 0.5 ulp maximum error is the best you could hope for, since
! this corresponds to always rounding to the nearest representable
! floating-point number. Value must be positive - if a negative
! value is supplied, the absolute value is used.
! If not specified, the default value is 1.
!
! James Van Buskirk and James Giles suggested this method for floating
! point comparisons in the comp.lang.fortran newsgroup.
