Why is the output not consistent? How can we verify accuracy without having to use decimal places or double?
[code]#include <stdio.h>
int main(int argc, const char * argv[]) {
// This is a BNR Challenge.
// The challange first says to declare two variable of type float
// and assign each of them a number with a decimal point
float piNumber = 3.140;
float answerEverything = 42.0;
// Next, declare another variable of type double and assign it the sum of two floats
double sumFloats = piNumber + answerEverything;
// Next print the result using printf()
printf("The sum of the two floats is %f.\n", sumFloats);
printf("The sum with 2 decimal places is %.2f.\n", sumFloats);
// Setting smaller variables to see if the .9999 thing happens still
float testOne = 100.110;
float testTwo = 2.0;
double sumTests = testOne + testTwo;
printf("The test sum is %f.\n", sumTests);
//Of course, return 0
return 0;
}

[quote]Output: The sum of the two floats is 45.139999.
The sum with 2 decimal places is 45.14.
The test sum is 102.110001.[/quote]
