Type casting

[Bruno <brunomendoza@gmail.com>]

Hi, 

I have a small mess with the conversion of numeric types in the
following program 

http://paste.ideaslabs.com/show/q6vOGqlyYJ 

I really do not know how to interpret the operation (E / 2) because
although the operation is composed of two numbers such as "Positive"
outcome can be of type "Float" and, of course, the "Integer" (attribute)
returns an integer but the closest to real number and what 
need my program is that it returns the integer part regardless 
the decimal part. 

I tried creating a small building under the following function

but by requiring Float type parameters for the algorithm does not work 
prev. 

Can anyone shed some light on the conversion rate and the 
problem presented to me? 

Thank you.
