math decis dont coope with the editor?

[alexho]

i have a simple problem with we when i want to convert numbers with large decimal places, i simply cannot.
for example
123456789/24
=ans*24 should equal 123456789 but it ends up just being 12345678 in the editor.

i am using real number variable, but it seems to me that it only goes to 2 or 3 decimal places.

i just hope there is a work around for this or not ?
how can i get my values to be more precise? is there a math function that can convert large values accurately int he editor?

I find it unlikely that 123456789 is becoming 12345678, but otherwise this isn't a bug. The "real" type is not precise.

which variable type is precise i only see real and integer for variables? is there another math function that can compute larger numbers exactly?

i do have proof:

i have tried it with 12345 a five digit number and it seems to work, i just think large values come out not to compute to the right number in the editor its the restriction of decimals so the accuracy is off. o well..

Integers are fine as long as values are between -2147483648 and 2147483648. Reals are a little trickier. Generally, you will get an acceptable level of precision if you avoid large numbers with long fractional parts.
