Weird integer arithmethics

[asodja]

It wrongly calculates the expressions like 3*(2^p) => 3, when p == 1' or 3*(2^{p) => 27, when p == 3'.}

In all cases is p of type Integer. If it is declared as Real, the results of expression evaluations are correct.
Expression is also correctly evaluated when integer value is inserted instead of variable, e.g. `3*(2^{3) => 24'.}

The example class is attached and this error appears in omc shell, for example:

{{>>> p := 3

3

3*(2^p)

27
}}

[asodja]

The error seems to be a swap of base and exponent in some rule. Instead of {{p := 5; 3*(2^{p) => 96}} is calculated {{3*(p}2) => 75}}.

This was a problem with one of the simplification rules, which has now been corrected.
