-      REAL FUNCTION R1MACH (I)
-      IMPLICIT NONE
-      INTEGER :: I
-      REAL :: B, X
-!***BEGIN PROLOGUE  R1MACH
-!***PURPOSE  Return floating point machine dependent constants.
-!***LIBRARY   SLATEC
-!***CATEGORY  R1
-!***TYPE      SINGLE PRECISION (R1MACH-S, D1MACH-D)

-!***DESCRIPTION
-!
-!   R1MACH can be used to obtain machine-dependent parameters for the
-!   local machine environment.  It is a function subprogram with one
-!   (input) argument, and can be referenced as follows:
-!
-!        A = R1MACH(I)
-!
-!   where I=1,...,5.  The (output) value of A above is determined by
-!   the (input) value of I.  The results for various values of I are
-!   discussed below.
-!
-!   R1MACH(1) = B**(EMIN-1), the smallest positive magnitude.
-!   R1MACH(2) = B**EMAX*(1 - B**(-T)), the largest magnitude.
-!   R1MACH(3) = B**(-T), the smallest relative spacing.
-!   R1MACH(4) = B**(1-T), the largest relative spacing.
-!   R1MACH(5) = LOG10(B)
-!
-!   Assume single precision numbers are represented in the T-digit,
-!   base-B form
-!
-!              sign (B**E)*( (X(1)/B) + ... + (X(T)/B**T) )
-!
-!   where 0 .LE. X(I) .LT. B for I=1,...,T, 0 .LT. X(1), and
-!   EMIN .LE. E .LE. EMAX.
-!
-!   The values of B, T, EMIN and EMAX are provided in I1MACH as
-!   follows:
-!   I1MACH(10) = B, the base.
-!   I1MACH(11) = T, the number of base-B digits.
-!   I1MACH(12) = EMIN, the smallest exponent E.
-!   I1MACH(13) = EMAX, the largest exponent E.
