Could anyone give me a list of intrinsic names.
eg.
COS SIN DCOS DSIN CHAR ...
My manual lists everything but intrinsics, is it because the Fortran
standard doesn't define them - so it is system dependant?

In your posting you ask: Are any of these standard? [...] >MAX0 >AMAX1 >DMAX1 >AMAX0 >MAX1 >MIN0 >AMIN1 >DMIN1 >AMIN0 >MIN1 All these appear in a FORTRAN IV manual (IBM System/360 and System/370 GC28-6515-10 June 1981) I've had for some time. All are listed as ` "ANS FORTRAN Intrinsic functions" whereas simple "MAX" is flagged as an extension. To list the differences would take too much typing but for example MAX and MAX0 perform the same function (extract the maximum form a list of integers) whereas MAX1 extracts the maximum of a list of reals but returns an integer (it's not clear from the manual if the integer is obtained by rounding/chopping/guessing...) and AMAX1 extracts the maximum from a list of reals. Hope this is some help. --------> Peter Monk *************************** * Dept of Math Sci * * University of Delaware * * monk@math.udel.edu * *************************** ------------------------------------------------------------

The list would be shorter if you limited it to generic function names, which
are the only ones that should be used in new programs.
=>MAX0
=>AMAX1
=>DMAX1
=>AMAX0
=>MAX1
=>MIN0
=>AMIN1
=>DMIN1
=>AMIN0
=>MIN1
All of the above should be replaced by the generic name MAX.
The names you gave are called "specific intrinsic function names" by the
standard. Although they are still recognized, they should not be used in new
programs.
=>TRANSCENDENTALS:
=>SQRT
=>DSQRT
=>CSQRT
=>EXP
=>DEXP
=>CEXP
=>ALOG
=>DLOG
=>CLOG
=>ALOG10
=>DLOG10
=>TRIG:
=>SIN
=>DSIN
. . .
Something is bogus about your classification scheme, besides the fact that you
included specific names like DSQRT.
The SQRT (DSQRT, CSQRT) function, which you list under "transcendentals", is
not transcendental. The trig functions, and several others in your list that
you do not classify as "transcendental," are in fact transcendental.
Transcendental, by definition, means "not algebraic."

My Fortran guide doesn't mention it. What does it do? Yes. To quote ANSI X3.9-1978 [ = ISO 1539-1980(E), according to the cover], page 15-26: "For a of type real, IFIX(a) is the same as INT(a)" > > >IDINT > >FLOAT > >SINGL > > Are any of these standard? Yes. IDINT is specific intrinsic for double to integer conversion. FLOAT is real to integer (synonym for REAL, as far as I know). SNGL is specific for double to real conversion. > > [...] > >MAX0 > >AMAX1 > >DMAX1 > >AMAX0 > >MAX1 > >MIN0 > >AMIN1 > >DMIN1 > >AMIN0 > >MIN1 > > My Fortran book only mentions MAX and MIN as standard.

If your compiler supports Fortran77, as defined by ANSI and ISO, then it should understand all of these. > Marc R. Roussel > mroussel@alchemy.chem.utoronto.ca I think the confusion is arising because of the distinction between specific and generic intrinsic functions. For example, as above, IDINT is the specific name for the intrinsic function for converting a double to an integer by truncation. INT is both the specific name of the function for truncating a real to an integer, and also serves as the generic name for the function that converts reals _or_ doubles to integers. In other words, if you use INT(a), the compiler is supposed to figure out whether to use the specific INT or the specific IDINT depending on the type of the argument "a", if I understand the standard correctly. For the record, I append here a list of the generic and specific intrinsic functions as listed in Table 5, page 15-22 of ANSI X3.9-1978. For descriptions and argument types, see the standard or (I hope) your compiler documentation. And please don't ask me to explain the logic behind why some are listed only as generics, some as specifics with no generics, etc. There are probably readers of this group who were on that committee and could explain far better than I could. (Sorry if this list makes for a rather lengthy posting... And I hope I didn't miss any or introduce too many typos!)

In the discussion on intrinsic functions you say: >According to your statement, anything NOT algebraic....well >SQRT is not an algebraic function......TRIG functions are.... this is not correct. An ALGEBRAIC function of one variable is the solution of a polynomial equation in two variables. Thus x-y**2=0 has the solution y=sqrt(x). Thus SQRT is an algebraic function. Anything that is not algebraic is TRANSCENDENTAL.

Neither ININT (which appeared in Shawn's article), nor IDINT, cited by Marc, nor SINGL are standard. I think ININT is a typo for IDNINT, and SINGL is a typo for SNGL, both of which are standard. In addition to those cited by Shawn, MAX, MIN, DBLE and CMPLX are also required by the f77 standard. The following names are supposed to be "generic" names, and work with various argument types: INT, REAL, DBLE, CMPLX, AINT, ANINT, NINT, ABS, MOD, SIGN, DIM, MAX, MIN, SQRT, EXP, LOG, LOG10, SIN, COS, TAN, ASIN, ACOS, ATAN, ATAN2, SINH, COSH, and TANH. The rest of the names are specific names for various argument combinations. In the MAX/MIN world, 0 implies a integer arguments, 1 implies real arguments; A implies a real result, D implies a double result (and double arguments). The functions AMAX0/AMIN0 (integer argument, real result) and MAX1/MIN1 (real argument, integer result) aren't accessible through the generic MAX/MIN names. Any Fortran which doesn't have all of these isn't a full Fortran 77. -- Fred
