(f) X01

The values of the mathematical constants are:

X01AAF	(PI)	=	3.1415926535897932
X01ABF	(GAMMA) =		0.5772156649015329

(g) X02

The values of the machine constants are:

The basic parameters of the model

X02BHF =		2
X02BJF =		53
X02BKF =		-1021
X02BLF	=	1024
X02DJF	=	.TRUE.

Derived parameters of the floating-point arithmetic

X02AJF = Z'3CA0000000000001' ( 1.11022302462516D-16 )

X02AKF = Z'0010000000000000' ( 2.22507385850721D-308 )

X02ALF = Z'7FEFFFFFFFFFFFFF' ( 1.79769313486231D+308 )

X02AMF = Z'0010000000000000' ( 2.22507385850721D-308 )

X02ANF = Z'0020000000000000' ( 4.45014771701441D-308 )

Parameters of other aspects of the computing environment

X02AHF = Z'4300000000000000' ( 5.62949953421312D+14 )

X02BBF = 2147483647

X02BEF = 15

X02DAF = .FALSE.

(h) X04

The default output units for error and advisory messages for those routines which can produce explicit output are both Fortran Unit 6.

It is not possible to use the routines X04ACF and X04ADF with the f90 compiler.

(i) X05

The finest granularity of wall-clock time available on this system is one second, so the seventh element of the integer array passed as a parameter to X05AAF will always be returned with the value 0.

5. Documentation

Each supported NAG Fortran Library site is ordinarily provided with a printed copy of the NAG Fortran Library Manual (or Update) and Introductory Guide. Additional copies are available for purchase; please refer to the NAG websites or contact your local NAG Response Centre for current prices (see Section 6).

A full on-line version of the NAG Fortran Library Manual is supplied in the form of Portable
