ISGREATER(3) BSD Library Functions Manual ISGREATER(3)NAME
isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered -- compare two floating-point numbers
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <math.h>
int
isgreater(real-floating x, real-floating y);
int
isgreaterequal(real-floating x, real-floating y);
int
isless(real-floating x, real-floating y);
int
islessequal(real-floating x, real-floating y);
int
islessgreater(real-floating x, real-floating y);
int
isunordered(real-floating x, real-floating y);
DESCRIPTION
Each of the macros isgreater(), isgreaterequal(), isless(), islessequal(), and islessgreater() takes arguments x and y and returns a non-zero
value if and only if its nominal relation on x and y is true. These macros always return zero if either argument is not a number (NaN), but
unlike the corresponding C operators, they never raise a floating point exception.
The isunordered() macro takes arguments x and y, returning non-zero if either x or y is NaN. For any pair of floating-point values, one of
the relationships (less, greater, equal, unordered) holds.
SEE ALSO fpclassify(3), math(3), signbit(3)STANDARDS
The isgreater(), isgreaterequal(), isless(), islessequal(), islessgreater(), and isunordered() macros conform to ISO/IEC 9899:1999
(``ISO C99'').

Hi all!
Hi all!
I am working with a problem to find the smallest floating point number that can be represented.

So the first time I am getting o.1 which I wanted.But from the next... (4 Replies)

Does anyone know for sure how to tell whether the RHEL 3 / 4 / 5 server you're logged into is real or VMware, other than rpm -qa | grep -i vm?
And if the server is real, is there any way to tell from the OS level what kind of hardware you're on? I guess I'm looking for something analogous to... (2 Replies)
Is there a way to compare two floating points numbers in a bash script using perl? I've tried just using a bash if statement and it doesn't seem to support floating point numbers. Can the perl line read vars from bash then output a var to bash?
a=1.1 #from bash
b=1.5 #from bash

for example:
# I want to judge the value of $1 which should be $2<$1<$3.
temp0=`echo "$1 - $2" | bc`

echo OK
else
echo False

Please use code tags, thanks. (6 Replies)
I'm curious if there is any real difference between using " " or ' ' or no quotes at all. For example, I have a variable called EXTRACT_FILES. When I declare it, I set it to false... EXTRACT_FILES=false. I eventually use the variable later in the script (having set it to EXTRACT_FILES=true due to... (2 Replies)

Hello,
I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers. I need to find the smallest number in each row that is not 0.0. Numbers can be negative and they do not come in any particular order for a given... (9 Replies)
