C***BEGIN PROLOGUE I1MACH
C***DATE WRITTEN 750101 (YYMMDD)
C***REVISION DATE 890213 (YYMMDD)
C***CATEGORY NO. R1

C***PURPOSE Returns integer machine dependent constants
C***DESCRIPTION
C
C I1MACH can be used to obtain machine-dependent parameters
C for the local machine environment. It is a function
C subroutine with one (input) argument, and can be called
C as follows, for example
C
C K = I1MACH(I)
C
C where I=1,...,16. The (output) value of K above is
C determined by the (input) value of I. The results for
C various values of I are discussed below.
C
C I/O unit numbers.
C I1MACH( 1) = the standard input unit.
C I1MACH( 2) = the standard output unit.
C I1MACH( 3) = the standard punch unit.
C I1MACH( 4) = the standard error message unit.
C
C Words.
C I1MACH( 5) = the number of bits per integer storage unit.
C I1MACH( 6) = the number of characters per integer storage unit.
C
C Integers.
C assume integers are represented in the S-digit, base-A form
C
C sign ( X(S-1)*A**(S-1) + ... + X(1)*A + X(0) )
C
C where 0 .LE. X(I) .LT. A for I=0,...,S-1.
C I1MACH( 7) = A, the base.
C I1MACH( 8) = S, the number of base-A digits.
C I1MACH( 9) = A**S - 1, the largest magnitude.
C
C Floating-Point Numbers.
C Assume floating-point numbers are represented in the T-digit,
C base-B form
C sign (B**E)*( (X(1)/B) + ... + (X(T)/B**T) )
C
C where 0 .LE. X(I) .LT. B for I=1,...,T,
C 0 .LT. X(1), and EMIN .LE. E .LE. EMAX.
C I1MACH(10) = B, the base.
C
C Single-Precision
C I1MACH(11) = T, the number of base-B digits.
C I1MACH(12) = EMIN, the smallest exponent E.
C I1MACH(13) = EMAX, the largest exponent E.
C
C Double-Precision
C I1MACH(14) = T, the number of base-B digits.
C I1MACH(15) = EMIN, the smallest exponent E.
C I1MACH(16) = EMAX, the largest exponent E.
C
C To alter this function for a particular environment,
C the desired set of DATA statements should be activated by
C removing the C from column 1. Also, the values of
C I1MACH(1) - I1MACH(4) should be checked for consistency
C with the local operating system.
