#
# The program evaluate the value of expressions 
# which contain floating-point, interval and fuzzy numbers.
#
# 1+2*(2+5)                    Floating-point expression.
# [1,2]+[2,3]                  Interval numbers are defined using upper (Xmax) and lower (Xmin) bounds e.g. [Xmin, Xmax].
#
# By default the + operator is assumed between the lines.
# These two lines are equivalent to the expression 1+2*(2+5) + [1,2]+[2,3].
#
# {[0,1,5],   [1,2,3]}         Fuzzy number is a collection of alpha-cuts.
#                              Each alpha-cut is a triple [alpha,Xmin,Xmax]
#{[0,1,5],   [1,2,3]}+[1,2]*2  Composite expression can have floating-point, interval and fuzzy numbers.
#
# It is possible to add an operator between the lines.
#
# 1+2                    
# *
# [1,2]+[2,3]
#
# These two lines are equivalent to the expression 1+2 * [1,2]+[2,3].
#
# The final result is a value of the expression which is created 
# from all the data in the data file. 
#
# The code in the data file can be changed manually.
