If you have something like
x := 4
in embedded Calc, then you can use calc-store (s s RET) to assign the
value 4 to x in Calc. You can then use calc-evalto (s =) to get
x := 4 =>
In your case, though, while this would assign 14.5 to myVariable in
Calc, it would also leave you with
myVariable := 14.5 => 14.5
in embedded Calc.

If a variable has a value in Calc and it isn't overridden in embedded
Calc, then the variable will have the same value in embedded Calc.
