C++ :: Scientific Notation To Decimal?
Mar 12, 2014I just wrote code that is a program for a relativity calculator. However many of my outputs (because the values tend to be large) end up in scientific notation. Although useful, its not great for the laymen, or nice looking.
How can I change it so that output is not in scientific notation? here is the code:
// This program/converter is designed to find the desired 'real' values using Einstein's theory of relativity
#include<iostream>
#include<math.h>
#include<stdlib.h>

C++ :: Stop Scientific Notation
Jul 15, 2013double number = 10000000;
int range;//the length of the string result
string result;//holds the number in a string
ostringstream convert; //stream used for the conversion
convert << number;
result = convert.str();
range = result.length();
I'm trying to convert a double to a string and when the number goes to ten million it goes to scientific notation and it shows it in the string. How do I stop it from do that?

Mar 28, 2013I have this simple code here:

I get the answer 5.94 (which is what I'm looking for). I can't work out why the first example is not outputting a decimal number. I have set the variables as a double so I just can't see why this is not working for me.

C++ :: File Input / Output - Getting Highest And Lowest Number From A List Of 7 Numbers
Apr 16, 2013I am currently confused on how to get the highest and lowest number from a list of 7 numbers for a File Output. Lets say i have 165 19 654 816 654 987 324. How would i get the 987 for the highest and the 19 as the lowest? Those numbers are not fixed numbers, i need to be able to input any combination of numbers and still be able to get the highest and lowest numbers from the list of 7 numbers.

C :: Simple Decimal Input To Binary Output
Jun 22, 2013I am learning c because I want to get back into programming microcontrollers, which I previously did in assembly. I wanted to make something fairly tight in terms of program memory and RAM to show me an output in binary form. When you are troubleshooting a file register or serial interface when you can see the actual bit values (on a small LCD for a micro-controller) and compare it to a datasheet.
Code:
#include <stdio.h>
#include <math.h>
int main() {
int i;
int decimaltoconvert;
int convertingarray[7];
int convertingarray2[7];

Also, how might I go about putting that into a function that I could call?

C++ :: Accept Signed Decimal Integer As Input And Output In Binary
Jan 29, 2015Write a C++ application program to accept a signed decimal integer as input and output the equivalent 2s complement version in 16-bit binary. Include a space between every four bits in the output string. The input will only be processed by the application if it falls in the valid range that can be represented in 2s complement format with 16 bits. The range of a decimal number from - to + is -32768 to 32767.

Oct 11, 2014 My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>

Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...

int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";

C :: Binary Number To Decimal
Mar 30, 2014I am very new to programming and have been working on a program that can receive decimals or binary numbers and convert them. The decimal --> binary works fine. For some reason I cannot figure out I cannot get the "BinaryToDecimal" function to perform. By putting a "printf" into the for-loop.
Code:
#include <stdio.h>#include <string.h>

C/C++ :: Binary Number Into Decimal?
Sep 10, 2014I have a code and am asked to modify it so that it will take as input as unsigned binary number up to 16 digits in length and convert it into its equivalent decimal number and output that decimal number.
All I know is that I use library function strlen() in <cstring> to calculate the length of the input string.
I also know I have to use something called pow(2,4);
//pow (); is found in cmath
I was told to use sum = sum >>16-l; (l is the length of />/>

Maybe, convert to string than remove the first character from the string than convert the string back to an int?
