NAME
     TINY - Returns the smallest positive value for a real argument

SYNOPSIS
     TINY ([X=]x)

IMPLEMENTATION
     UNICOS, UNICOS/mk, IRIX systems

     CF90, MIPSpro 7 Fortran 90

STANDARDS
     Fortran

DESCRIPTION
     The TINY intrinsic function returns the smallest positive number in
     the real number model that represents number of the same type and kind
     type parameter as the argument.  For more information on the real
     number model, see the MODELS(3I) man page.  It accepts the following
     argument:

     x         Must be of type real.  It may be scalar or array valued.

     TINY is an inquiry function.  The name of this intrinsic cannot be
     passed as an argument.

RETURN VALUES
     The result is a scalar with the same type and kind type parameter as
     x.  The result has the value
      e sub min-1
     b           , where b and e
                                 min
     (represented as "e sub min" in the previous equation) are as defined
     in the real number model, which represents numbers of the same type
     and kind type parameter as x.

EXAMPLES
     On UNICOS systems, TINY(X) has a value that approximates
      -8188
     2      for real X.

     On CRAY T90 systems that support IEEE arithmetic, TINY(X) has values
     that approximate the following:
        -125
     * 2     for real (KIND=4) X
        -1021
     * 2      for real (KIND=8) X
        -16381
     * 2       for real (KIND=16) X

     On UNICOS/mk systems, TINY(X) has values that approximate the
     following:
        -125
     * 2     for real (KIND=4) X
        -1021
     * 2      for real (KIND=8) X

     On IRIX systems, TINY(X) has values that approximate the following:
        -125
     * 2     for real (KIND=4) X
        -1021
     * 2      for real (KIND=8) X
        -967
     * 2     for real (KIND=16) X
