*DECK I1MACH INTEGER FUNCTION I1MACH (I) C***BEGIN PROLOGUE I1MACH C***PURPOSE Return integer machine dependent constants. C***LIBRARY SLATEC C***CATEGORY R1 C***TYPE INTEGER (I1MACH-I) C***KEYWORDS MACHINE CONSTANTS C***AUTHOR Fox, P. A., (Bell Labs) C Hall, A. D., (Bell Labs) C Schryer, N. L., (Bell Labs) C***DESCRIPTION C C I1MACH can be used to obtain machine-dependent parameters for the C local machine environment. It is a function subprogram with one C (input) argument and can be referenced as follows: C C K = I1MACH(I) C C where I=1,...,16. The (output) value of K above is determined by C the (input) value of I. The results for various values of I are C 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, the desired C set of DATA statements should be activated by removing the C from C column 1. Also, the values of I1MACH(1) - I1MACH(4) should be C checked for consistency with the local operating system. C C***REFERENCES P. A. Fox, A. D. Hall and N. L.
