I have to write a c program which takes a 3 digit number n and calculates the value of (2^n)+1 and then determines the number is prime or not.
I have tried to first calculate the value of 2^n and then adding one to it and then apply the logic of prime number.
but the ultimate problem is that if n is a 3 digit number for example 100
then 2^100 becomes a huge number for which my program is returning the same value of 2^100 and 2^100+1
for 2^50 and 2^50+1 it returns correct values with the diff of 1.
Please help me out here.
Hi,
Was wondering if you could give me an example of extracting a 10 digit number from 5 txt files using a regular expression (the number is always different ) and storing the numbers in variables
Thanks

i am new to shell scripting. i want to keep on increamenting a 6 digit number. For eg. 000000 + 1 = 000001 But instead of 000001 i get only 1. How do i do this ? Pls help. (8 Replies)
how can i list all files in my home directory that have a 4 digit id number, the line number where the id is located and the id itself not printing the entire line? (5 Replies)
I want to write/print a number through a shell script up to its last significant digit (LSD) after the decimal point.
Say,
x=10.00056000000000000
I want to print x as x=10.00056.
Note that x can be any thing so I cannot know the position of the LSD always.
Thanks. (16 Replies)
Hello Team,
i have a file test1.txt, in which i have to grep only the 6 digit number from it,
Could you pls help in this.
$cat test1.txt
<description>R_XYZ_1.6 r370956</description>
$ grep "\{6\}" test1.txt
<description>R_XYZ_1.6 r370956</description>
i need output as 370956.

Dear All,
Lets say I have a number with following format:
####.12e-##
now I want to compare place holder in position 1 and 2.
How can I do that?
Note: My number is stored in a variable say var.
example:
var=9999.12e-05
Thanks & Regards,

YAGI(5) File Formats Manual YAGI(5)NAME
yagi - yagi binary output format
DESCRIPTION
This manual page describes the output format of the file created by the Yagi-Uda project's yagi program. The file is a binary file with a
header of 100 bytes. The header consists of:
offset(bytes) information data-type
0 elements int
4 driven int
8 parasitic int
12 min_frequency double
20 max_frequency double
28 design frequency double
36 step_frequency double
44 angular_step double
52 0 double
92 0 double
Following the header, there starts the coordinates(x,y,l) of each
element and the voltage applied to each element. Then we write
the element currents one after the other, at each frequency.
Hence the element currents will be written 12,000 times with a
3 element yagi analysed at 4,000 different frequencies. All complex
data is stored in a structure of type fcomplex, defined as:
struct fcomplex {double real, double imaginary};
offset(bytes) information data-type
100 x1 double /* coordinates */
108 y1 double
116 l1 double
100+(n-1)*24 x_n double
100+(n-1)*24+8 y_n double
100+(n-1)*24+16 l_n double
-------------- Repeated for each element.
100+24*elements Voltage1 fcomplex /* voltage */
100+24*elements+(n-1)*16 Voltage_n fcomplex
-------------- Repeated for each element n at each frequency step f.
100+40*elements Current1@f1 fcomplex /* current */
100+40*elements+(n-1)*16 Current_n@f1 fcomplex
100+56*elements Current@f2 fcomplex
100+40*elements+(n-1)*16 Current_n@f2 fcomplex
