C***DESCRIPTION
|
||||
INTEGER I
|
||||
C
|
||||
C D1MACH can be used to obtain machine-dependent parameters
|
||||
C for the local machine environment. It is a function
|
||||
C subprogram with one (input) argument, and can be called
|
||||
C as follows, for example
|
||||
C
|
||||
C D = D1MACH(I)
|
||||
C
|
||||
C where I=1,...,5. The (output) value of D above is
|
||||
C determined by the (input) value of I. The results for
|
||||
C various values of I are discussed below.
|
||||
C
|
||||
C D1MACH( 1) = B**(EMIN-1), the smallest positive magnitude.
|
||||
C D1MACH( 2) = B**EMAX*(1 - B**(-T)), the largest magnitude.
|
||||
C D1MACH( 3) = B**(-T), the smallest relative spacing.
|
||||
C D1MACH( 4) = B**(1-T), the largest relative spacing.
|
||||
C DOUBLE-PRECISION MACHINE CONSTANTS
|
||||
C D1MACH( 1) = B**(EMIN-1), THE SMALLEST POSITIVE MAGNITUDE.
|
||||
C D1MACH( 2) = B**EMAX*(1 - B**(-T)), THE LARGEST MAGNITUDE.
|
||||
C D1MACH( 3) = B**(-T), THE SMALLEST RELATIVE SPACING.
|
||||
C D1MACH( 4) = B**(1-T), THE LARGEST RELATIVE SPACING.
|
||||
C D1MACH( 5) = LOG10(B)
|
||||
C
|
||||
C Assume double precision numbers are represented in the T-digit,
|
||||
C base-B form
|
||||
C
|
||||
C sign (B**E)*( (X(1)/B) + ... + (X(T)/B**T) )
|
||||
C
|
||||
C where 0 .LE. X(I) .LT. B for I=1,...,T, 0 .LT. X(1), and
|
||||
C EMIN .LE. E .LE. EMAX.
|
||||
C
|
||||
C The values of B, T, EMIN and EMAX are provided in I1MACH as
|
||||
C follows:
|
||||
C I1MACH(10) = B, the base.
|
||||
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 D1MACH(1) - D1MACH(4) should be checked for consistency
|
||||
C with the local operating system.
