here is a part of my source code. This part is reponsible to get the minimun of a few values:
This works fine while the values are > 1. If the values are < 1 than this code is not able to identify the minimun.
I've already tried to set the MAX as float, but that didn't work, too.
I am trying to compare 2 float values using if
the foll code does not work
a=1.4
b=1.6
if test $a -gt $b
then
echo "$a is max"
else
echo "$b is max"
fi
does -gt work for floating point numbers, if not how do go about for my requirement? can i use bc ? pls help
thanks in advance... (2 Replies)
Hi
I know its a dumb question but can any one please explain me the difference of executing a shell script in the following 2 ways.
. script.sh
sh script.sh
I have a problem if I execute the following code as sh script.sh
DB_CNT_ALW=0.20
SCT_VAR=0.05

Good morning,
I'm testing the use of ceilf:
/*Filename: str.c*/
#include <stdio.h>
#include <math.h>
int main (void)
{
float ceilf(float x);
int dev=3, result=0;
float tmp = 3.444f;
printf("Result: %f\n",ceilf(tmp));
return 0;

Today I spent longer than I'd like to admit figuring out how to write a Bourne shell IF statement that tests a FLOAT value before executing a block of statements. Here's the solution I found, which invokes bc. Hope this will come in handy for someone:
value =
testval =
if
then

I have a file with 2 columns . One of the line looks like the following.
Is it possible to convert every float no in column 2 to integer.

:confused:We have two servers one active and one stand by
as follows Active 202.61.9.9
Stand by 202.61.9.10
Float IP 202.61.9.8
What is use of this float IP?
How it is configured? (1 Reply)
Hi,
I have small problem to print float value in the fallowing code
float Cx, W,f=250000, Cr=92.00,pi=3.14;
W=2*pi*f;
Cx = 1/W.Cr; //Cx value will be come around like 7.07E-9.
printf("capacitance value: %.10f",Cx);
I am trying to print Cx value using above code but it was not... (3 Replies)

max
MAX(3) 1 MAX(3)max - Find highest valueSYNOPSIS
mixed max (array $values)
DESCRIPTION
mixed max (mixed $value1, mixed $value2, [mixed $...])
If the first and only parameter is an array, max(3) returns the highest value in that array. If at least two parameters are provided,
max(3) returns the biggest of these values.
Note
Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be com-
pared to an integer as though it were 0, but multiple string values will be compared alphanumerically. The actual value returned
will be of the original type with no conversion applied.
PARAMETERS
o $values
- An array containing the values.
o $value1
- Any comparable value.
o $value2
- Any comparable value.
o $...
- Any comparable value.
RETURN VALUES max(3) returns the parameter value considered "highest" according to standard comparisons. If multiple values of different types evaluate
as equal (e.g. 0 and 'abc') the first provided to the function will be returned.
EXAMPLES
Example #1
Example uses of max(3)
<?php
echo max(2, 3, 1, 6, 7); // 7
echo max(array(2, 4, 5)); // 5
// The string 'hello' when compared to an int is treated as 0
// Since the two values are equal, the order they are provided determines the result
echo max(0, 'hello'); // 0
echo max('hello', 0); // hello
// Here we are comparing -1 < 0, so 'hello' is the highest value
echo max('hello', -1); // hello
// With multiple arrays of different lengths, max returns the longest
$val = max(array(2, 2, 2), array(1, 1, 1, 1)); // array(1, 1, 1, 1)
// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 5 > 4
$val = max(array(2, 4, 8), array(2, 5, 1)); // array(2, 5, 1)
// If both an array and non-array are given, the array will be returned
// as comparisons treat arrays as greater than any other value
$val = max('string', array(2, 5, 7), 42); // array(2, 5, 7)
// If one argument is NULL or a boolean, it will be compared against
// other values using the rule FALSE < TRUE regardless of the other types involved
// In the below example, -10 is treated as TRUE in the comparison
$val = max(-10, FALSE); // -10
// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE
$val = max(0, TRUE); // TRUE
