Hi

I've got a problem with an Ada program(surprise ;D).
With this line:

x := sol_Ty((var_Ar(f)*var_Ar(b))-(var_Ar(e)*var_Ar(c))/z);
-- x : sol_Ty := (f*b - e*c) / z;

I get the following errors:
 > ambiguous universal_fixed_expression
 > possible interpretation as type "Standard.duration"
 > possible interpretation as type "sol_Ty" defined at line 8
The minus in the middle is highlighted after the errors.

var_Ar is an array of the type sol_Ty and x is also sol_Ty. sol_Ty 
definition is a decimal fixed point:
 > type sol_Ty   is delta 0.01 digits 18;
I never worked with duration so can anyone tell me (or link something) 
what it is and why it can be missinterpreted in this case? And how i can 
GENERALLY solve it?!

thx already
