C :: Float Variables Not Able To Be Multiplied With Each Other

Apr 5, 2013

why does the 2 variables, loanAmt and intRatem not work when they are multiplied together. The question is " Write a program that calculates the remaining balance on a loan after the first, second and third monthly payments. "

Code:

#include <stdio.h>
void a5()
{
float loanAmt, intRate, intRatem, dintRate, payment, pay1, pay2, pay3,test;
printf("Enter amount of loan:");
scanf("%f", &loanAmt);
}

How to print to the screen the value of n after it has been multiplied.

For example: if I use cout << "n: " << n << " power: " << power << "
"; I

can see the variable "power" decrementing by 1, but I don't see the variable "n" incrementing with its new value after it has been multiplied by n * n.

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 :: Round Off Float To Integer

Mar 10, 2013

I have a float values I'd like to round off to the nearest integer value.

That is to say, if the float value is 44.234533, the integer value should be 44. If the float value is 44.682101, the integer value should be 45.

How do I do this?

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

Jan 16, 2014

Unless I'm missing something, it's now possible(ish)? A little concept is below, very rough around the edges. Still though, if this is valid by standard C++, why can't we have built-in support for float / double template parameters?

#include <tuple>
template<int Numerator, int Denominator>
struct Float {
constexpr static float value()
