CEILING and FLOOR functions
Hi all,

Does anyone know how to simulate a ceiling or floor function in UNIX? OS is Solaris. I tried the suggestion from an old forum but it is giving me error as below:

Code:
server01[]/tmp$: echo "7.2" | awk '{printf("%d\n",$0+=$0<0?0:0.999)}'
awk: syntax error near line 1
awk: illegal statement near line 1

Am looking for something "simple", echo "7.123" | ceiling or echo "7.123" | floor that should return 8 or 7 respectively or something like that. Won't mind having to use awk i fneed be, but not sure how to call the function. I've also tried the one below but same error:

Code:
server01[]/tmp$: echo "7.2" | awk 'function ceil(valor) { return (valor == int(valor)) ? valor : int(valor)+1 } { printf "%d", ceil($1) }'
awk: syntax error near line 1
awk: bailing out near line 1

Any suggestion will be much appreciated. Thanks in advance.

floorf

FLOOR(3)						     Linux Programmer's Manual							  FLOOR(3)

NAME

       floor, floorf, floorl - largest integral value not greater than argument

SYNOPSIS

       #include <math.h>

       double floor(double x);
       float floorf(float x);
       long double floorl(long double x);

DESCRIPTION

       These functions round x down to the nearest integer.

RETURN VALUE

       The rounded integer value. If x is integral or infinite, x itself is returned.

ERRORS

       No errors other than EDOM and ERANGE can occur.	If x is NaN, then NaN is returned and errno may be set to EDOM.

NOTES

       SUSv2  and POSIX 1003.1-2001 contain text about overflow (which might set errno to ERANGE, or raise an exception).  In practice, the result
       cannot overflow on any current machine, so this error-handling stuff is just nonsense.  (More precisely, overflow can happen only when  the
       maximum value of the exponent is smaller than the number of mantissa bits.  For the IEEE-754 standard 32-bit and 64-bit floating point num-
       bers the maximum value of the exponent is 128 (resp. 1024), and the number of mantissa bits is 24 (resp. 53).)

CONFORMING TO

       The floor() function conforms to SVID 3, POSIX, BSD 4.3, ISO 9899.  The other functions are from C99.
