[Tutor] Decimal fixed point representation

[Dinesh B Vadhia]

Hi Alan

That's right, it is the Decimal module I'm trying to understand.  And, it is how to represent a decimal floating point number as a common/vulgar fraction eg 1.234 = 1234/1000.  How do you do this using the Decimal module?  The motivation is to avoid floating point calculations and use integers only (don't ask why!).  Cheers!

Dinesh

I'm not sure what you mean by that.

Is it the use of the Decimal module you are querying?

Is it how to represent a ecimal fraction as an 
integer - ie how to lose the numbers after the point?

Is it how to represent it as a common/vulgar fraction
eg 1.234 = 1234/1000

Or something else?

It is possible that you are barking mad I suppose. 

As to whether what you are asking about decimals 
is possible, that depends on what you are actually 
asking :-)
