Hi,
I wrote this script
awk -F"\t" '{if ((($1 == 586) || ($1 == 68030)) && (($2/1024) < 512)) print $0"\t"(512-($2/1024))"\t"(512-($2/1024))/256}' pcs.txt

Hi, I got an easy problem for you but really difficult for me 'cause I am pretty new to this field
I got header file <math.h> included in my .c file , then I write the code as below:

then I cc temp.c
it says like this

I am trying to do some math, so that I can compare the average of six numbers to a variable.
Here is what it looks like (note that when I divide really big numbers, it isn't a real number):

I have
int miles, yards;
float kilometers;
float kilometers2;
miles = 26;
yards = 385;
kilometers = 1.609 * (miles + yards / 1760.0);
where int/float remains a float. How ever if I change it to

I am struggling with scripting this challenge a friend and I have.
You have file1 and its contents is a single number
you have file 2 and its contents are a different number
you want to add file1 to file2 and have the output be put into file3 (3 Replies)

bigrat
bigrat(3pm) Perl Programmers Reference Guide bigrat(3pm)NAME
bigrat - Transparent BigNumber/BigRationale support for Perl
SYNOPSIS
use bigrat;
$x = 2 + 4.5,"
"; # BigFloat 6.5
print 1/3 + 1/4,"
"; # produces 7/12
DESCRIPTION
All operators (inlcuding basic math operations) are overloaded. Integer and floating-point constants are created as proper BigInts or
BigFloats, respectively.
Other than bignum, this module upgrades to Math::BigRat, meaning that instead of 2.5 you will get 2+1/2 as output.
MODULES USED
"bigrat" is just a thin wrapper around various modules of the Math::BigInt family. Think of it as the head of the family, who runs the
shop, and orders the others to do the work.
The following modules are currently used by bignum:
Math::BigInt::Lite (for speed, and only if it is loadable)
Math::BigInt
Math::BigFloat
Math::BigRat
MATH LIBRARY
Math with the numbers is done (by default) by a module called Math::BigInt::Calc. This is equivalent to saying:
use bigrat lib => 'Calc';
You can change this by using:
use bigrat lib => 'BitVect';
The following would first try to find Math::BigInt::Foo, then Math::BigInt::Bar, and when this also fails, revert to Math::BigInt::Calc:
use bigrat lib => 'Foo,Math::BigInt::Bar';
Please see respective module documentation for further details.
SIGN
The sign is either '+', '-', 'NaN', '+inf' or '-inf' and stored seperately.
A sign of 'NaN' is used to represent the result when input arguments are not numbers or as a result of 0/0. '+inf' and '-inf' represent
plus respectively minus infinity. You will get '+inf' when dividing a positive number by 0, and '-inf' when dividing any negative number by
0.
METHODS
Since all numbers are not objects, you can use all functions that are part of the BigInt or BigFloat API. It is wise to use only the bxxx()
notation, and not the fxxx() notation, though. This makes you independed on the fact that the underlying object might morph into a differ-
ent class than BigFloat.
EXAMPLES
perl -Mbigrat -le 'print sqrt(33)'
perl -Mbigrat -le 'print 2*255'
perl -Mbigrat -le 'print 4.5+2*255'
perl -Mbigrat -le 'print 3/7 + 5/7 + 8/3'
perl -Mbigrat -le 'print 12->is_odd()';
