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'').

Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5).
I am trying to do this using... (1 Reply)
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,

Hi All,
I got this script that pulls the Amps value from our RPC's , I basiclly want to compare the valued with a "limit" value -- if the numbers match or are greater than the definded value ...do something. My problem is I cant seem to figure out how to compare floating points...

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
if... (3 Replies)

Hello,
How can I multiply two variables that contain floating point numbers.
For example, how can I get the value for c
a=2.165
b=3.234
c=a+3*b
Thanks,

Hi,
I need to understand the concept of floating IP and how can I get it working on my system. I am using Itanium boxes.
I am naive so please help me from the very basics. (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)
