calculating 2^601 results in "1.#INF00"

14 New Member
I am trying to find 2 at the power of 601, but my calculator doesn't have a large enough screen, so I decided to make a program for my computer to do this, but when I get to a high number the computer only prints : 1.#INF00. Is there any way to do it? My code is the fallowing:

Expand|Select|Wrap|Line Numbers
  1.  #include <iostream> 
  2. #include <stdio.h>
  3. #include <math.h>
  4.  
  5. using namespace std;
  6. float a;
  7. float x;
  8. float y;
  9.  
  10. main()
  11. {
  12. x=2;
  13. y=601;
  14. a = pow(x,y);
  15. printf("%f",a);
  16. cin.get();
  17.

Thanks, It Works Perfectly Now! Though I had to change the pow function and make one of my own that would work with NTL, But Now my program works just as I wanted!
Thanks to everybody who helped me!

Hi all, I have been struggling with a problem all day, I have been unable to come up with a working solution. I want to write a function which takes 2 unix timestamps and calculates the difference. I want it to return the difference in years, months, days, hours, minutes and seconds (a complete summary). Keeping into account of course that these are 2 real dates, I dont want it to work with 30.475 as an average number of days in a...

Firstly, sorry for the long post, but I've included a fair bit of sample data. Im doing a comparision of 10yr Bond prices and CPI adjustments, with an 18 week moving average of the CPI. I'm using a nested sub-query to calculate the moving average, but I'm having difficulty selecting exactly 18 data points (ie When I include the 'HAVING COUNT(C1.Closes) = 18' line, I get no results). Can anyone help?

Hi there, I am trying to make an OLAP cube on a table having two columns (datetime, Number_of_times_an_event_occured). My dimension is time and I want to measure the Min and Max times an event occured over time. I have no problem in calculating Maximum occurance of events over time. However, I have some NULL values in my Number_of_times_an_event_occured column, due to which I don't see any result when I try to calculate

I'm trying to get the results of binascii.crc32 to match the results of another utility that produces 32 bit unsigned CRCs. binascii.crc32 returns results in the range of -2**31-1 and 2**21-1. Has anyone ever worked out any "bit twiddling" code to get a proper unsigned 32 bit result from binascii.crc32? Output snip from test on three files: binascii.crc32=-1412119273, oldcrc32= 2221277246

I am calculating the phase of an IQ signal, which are polluted by AWGN gaussian noise. Thus, near pi/2, direct division of atan(Q/I) may yield outputs either +pi/2 or -pi/2. How do I handle this situation? Thanks.

I need to implement the following calculation: f = (a*b) + (c*d) where a,b,c,d are given double values and f is a double variable for the result I found out that using two different implementations gives two different results: 1) In the first implementation I compute the entire equation in memory 2) In the second implementation I store intermediate to variables, and then load them to compute the final result.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
