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."
