- IPMPAR PROVIDES THE INTEGER MACHINE CONSTANTS FOR THE COMPUTER
- THAT IS USED. IT IS ASSUMED THAT THE ARGUMENT I IS AN INTEGER
- HAVING ONE OF THE VALUES 1-10. IPMPAR(I) HAS THE VALUE ...
-
- INTEGERS.
-
- ASSUME INTEGERS ARE REPRESENTED IN THE N-DIGIT, BASE-A FORM
-
- SIGN ( X(N-1)*A**(N-1) + ... + X(1)*A + X(0) )
-
- WHERE 0 .LE. X(I) .LT. A FOR I=0,...,N-1.
-
- IPMPAR(1) = A, THE BASE.
-
- IPMPAR(2) = N, THE NUMBER OF BASE-A DIGITS.
-
- IPMPAR(3) = A**N - 1, THE LARGEST MAGNITUDE.
-
- FLOATING-POINT NUMBERS.
-
- IT IS ASSUMED THAT THE SINGLE AND DOUBLE PRECISION FLOATING
- POINT ARITHMETICS HAVE THE SAME BASE, SAY B, AND THAT THE
- NONZERO NUMBERS ARE REPRESENTED IN THE FORM
-
- SIGN (B**E) * (X(1)/B + ... + X(M)/B**M)
-
- WHERE X(I) = 0,1,...,B-1 FOR I=1,...,M,
- X(1) .GE. 1, AND EMIN .LE. E .LE. EMAX.
-
- IPMPAR(4) = B, THE BASE.
-
- SINGLE-PRECISION
-
- IPMPAR(5) = M, THE NUMBER OF BASE-B DIGITS.
-
- IPMPAR(6) = EMIN, THE SMALLEST EXPONENT E.
-
- IPMPAR(7) = EMAX, THE LARGEST EXPONENT E.
-
- DOUBLE-PRECISION
-
- IPMPAR(8) = M, THE NUMBER OF BASE-B DIGITS.
-
- IPMPAR(9) = EMIN, THE SMALLEST EXPONENT E.
-
- IPMPAR(10) = EMAX, THE LARGEST EXPONENT E.

-
- TO DEFINE THIS FUNCTION FOR THE COMPUTER BEING USED REMOVE
- THE COMMENT DELIMITORS FROM THE DEFINITIONS DIRECTLY BELOW THE NAME
- OF THE MACHINE
-
------------------------------------------------------------------------
-
- IPMPAR IS AN ADAPTATION OF THE FUNCTION I1MACH, WRITTEN BY
- P.A. FOX, A.D. HALL, AND N.L. SCHRYER (BELL LABORATORIES).
- IPMPAR WAS FORMED BY A.H. MORRIS (NSWC). THE CONSTANTS ARE
- FROM BELL LABORATORIES, NSWC, AND OTHER SOURCES.
