All,
A long time ago I posted a question about an algorithm that converts
floating point/double values to strings. I got one, but it does not work
all to well. I am using the float manager to convert strings to double.
That works perfectly. Can someone suggest a recommended method for
converting doubles to strings? I don't need the string in exponential
format, I just need the string to have 1 or 2 places precision. An example
of the problem I am seeing is the following.
User enters a number 1.2
I convert that to a double using the float manager. I get 1.2
I multiply that by 1000 to get 1200.
I store it in the database.
I read it back out.
Divide it by 1000 and get 1.2.
In my double to string conversion I get the integer portion using the
following code.
long iValue = ( long )1.2; // Gives me a 1.
I then subtract out the 1, i.e 1.2 - 1.0 to get .2
I then multiply that by 10 and get 2.0 (at least that's what the
debugger says I have!);
I then have the following code.
long dValue = ( long )2.0; // Gives me a 1. <-- This is the problem
I did not write this algorithm, I just used it! Is there a better way
to do this? The numbers I will need to convert will be in the following
range
0.5 to 999.9.
Thanks,
Brad
