how to compare 2 floating point no.

Hi, Could any one tell me how to compare to floating point no. using test command. As -eq option works on only intergers. i=5.4 if then echo "equal" else echo "not equal" fi here output will be equal even though no. are unequal. Thanks, ravi

awk, floating point and rounding

I had a person bring an interesting problem to me that appears to involve some sort of rounding inside awk. I've verified this with awk and nawk on Solaris as well as with gawk 3.1.5 on a Linux box. The original code fragment he brought me was thus: for (index=0; index < 1; index=index+.1) ...

fegetround

FEGETROUND(3)						   BSD Library Functions Manual 					     FEGETROUND(3)

NAME

     fegetround, fesetround -- floating-point rounding control

LIBRARY

     Math Library (libm, -lm)

SYNOPSIS

     #include <fenv.h>
     #pragma STDC FENV_ACCESS ON

     int
     fegetround(void);

     int
     fesetround(int round);

DESCRIPTION

     The fegetround() function determines the current floating-point rounding mode, and the fesetround() function sets the current rounding mode
     to round.	The rounding mode is one of FE_TONEAREST, FE_DOWNWARD, FE_UPWARD, or FE_TOWARDZERO, as described in fenv(3).

RETURN VALUES

     The fegetround() routine returns the current rounding mode.  The fesetround() function returns 0 on success and non-zero otherwise; however,
     the present implementation always succeeds.

SEE ALSO

     fenv(3), fpgetround(3), fpsetround(3)

STANDARDS

     The fegetround() and fesetround() functions conform to ISO/IEC 9899:1999 (``ISO C99'').

HISTORY

     These routines first appeared in FreeBSD 5.3.  They supersede the non-standard fpgetround(3) and fpsetround(3) functions.
