Fractions

[Anon]

Does anyone know of a clean and simple way/ and or a function that could take a decimal such as 0.75 and convert it somehow into an array containting the numerator and denominator of the fractional representation: example would be

$dec = 3.75;

$arrayOfStuff = magic_fraction_function($dec);

echo $arrayOfStuff[integer]."-".$arrayOfStuff[numerator]."/".arrayOfStuff[denominator];

thanks in advance;

Theire is too much possibilities for your example...

3.75 = 3+3/4

but

3.5 = Normally 3+1/2 it could also be 3+2/4 or 3+4/8....

You have to develop a function to resolve this.

1. Extract the integer.
2. Search the Common divisor for the decimal part.
3. How many times could this common divisor multiplied to reach the decimal value !

Remark... For the decimal par... work with integer.

For 0.1->0.9 work Base 10
For 0.01->0.99 work with 100
For 0.001->0.999 work with 1000
