How can I write an algorithm that given a floating point number, and attempts to represent is as accurately as possible using a numerator and a denominator, both restricted to the range of a Java byte?
The reason for this is that an I2C device wants a...

I recently ran into an issue where a query was causing a full table scan, and it came down to a column had a different definition that I thought, it was a VARCHAR not an INT. When queried with "string_column = 17" the query ran, it just couldn't use the...

Effectively rewrites the predicate as "CAST(order_number, INT) = 123456" which has two undesirable effects.

In another Bruce Eckels exercise in calculating velocity, v = s / t where s and t are integers. How do I make it so the division cranks out a float?
class CalcV { float v; float calcV(int s, int t) { v = s / t; return v; } //end calcV } public class PassObject...

Try:
v.
int operations usually return int, so you have to change one of the operanding numbers.

I am looking to refactor a c# method into a c function in an attempt to gain some speed, and then call the c dll in c# to allow my program to use the functionality.
Currently the c# method takes a list of integers and returns a list of lists of integers...

Or at least it would have.
I think the last line should be,
denominator /= u;
Also: you haven't written
numerator /= targetNumerator; denominator /= targetDenominator;

You are dividing by zero.

Consider the following signature in C#:
double Divide(int numerator, int denominator);
Is there a performance difference between the following implementations?

Hi there. I have some code to add fractions.
#include <stdio.h> #include <stdlib.h> struct frac { int enumerator; int denominator; }; typedef struct frac frac_t; frac_t *Add(frac_t *b1, frac_t *b2) { frac_t rfrac; frac_t *p; p = &rfrac; (*...
Answer Snippets (Read the full thread at stackoverflow):
Rfrac; frac_t *p; p = &rfrac; (*p).enumerator= ((*b1).enumerator* (*b2).denominator) + ((*b2).enumerator* (*b1).denominator); (*p).denominator= ((*b1).denominator* (*b2).denominator); return p; }
you.
