C++ :: Determining If A Float Is Odd / Even

Oct 22, 2013

determining if a value entered in loop is an odd or even number. Also, the value can't be int because it may be a decimal value(therefore i cant use the if(x%==0).

I need to replace the if(value%2 ==0) else num_even++ statement in my code with something else that will work with float to determine odd vs even.

#include <iostream>
using namespace std;
int main() {
int num_values;
float sum_values = 0;
int num_neg_values = 0;
int num_pos_values = 0;

C/C++ :: Integer And Float Value?

Feb 28, 2014

this is my code

#include<stdio.h>
main()
{

[Code]....

N=1st number M=2nd number(accrding to my prof we will name it N and M
ctr= increment of factorial of N, ctr2= increment of factorial of (N-M)

the problem is when i got the factorial of N / factorial of (N-M) i need to get the last non zero digit. so i use mod if it has zero in it. but mod can be only used with an int value. and when i change it to int value, the value of fact1 which is a float change

C++ :: 32 / 64 / 80 Bit Float Conversion?

Feb 14, 2012

I am looking for a math/big num library, that allows me to convert 32/64/80 bot float numbers to string and vice versa.

Precision & accuracy is of importance here, and since this is an IEEE standard, i have high hopes that there are libraries for this out there, which would save me the hassle of trying to implement this myself...

C :: Can't Show The Proper Float Value

Jul 7, 2014

I am working from my "ansi c" book by steven lawlor, page 73 program 2. write a program that accepts two numbers from the keyboard and prints the following information.

variables
first
second
execution
First number ? 7
Second number ? 2
the second goes into the first 3 times
with a remainder of 1.
the quotient is 3.5.

Code:
#include <stdio.h>
main() {
int first, second;
scanf(" %1i %1i", &first, &second);
printf("First number ? %1i

[Code] ....

//I included this as I had some error message come up
// before, not sure if this is correct though?
} it shows what is expected but I cant get the 3.5.

I have tried %f and variations of width/precision but still not luck. Also, when I click on the application and put in the variables I press enter, the program executes and disappears so I cant see the result. how do I get the program to stay up until I want to get rid of it?

C :: What Is Correct Way To Print A Float

Feb 17, 2013

I have a program that printf a float that is returned by a function like this:

Code:

printf("%3.1f
", myfloat());
...
float myfloat(void) {
code....
}

In w32 my program has been running ok, but when run in a w64, it crash at the printf. If I change the definition of the function to return double it runs ok. in printf format string - Wikipedia, the free encyclopedia , in the "type" section I see there is no definition to print a float, but %f is for double in fixed point.So the question is what is the correct way to printf a float? must I cast? or is it better to return double? if so, does it have a performance penalty?

C++ :: Float As Template Parameter

#include <tuple>

constexpr static float value()
