[TRNSYS-users] Float error on squaring

[henkwitte <henk.witte@groenholland.nl>]

Hello,

When I try to calculate in an equation the square of a difference of two 
variables in TRNSYS 15 like:

(value_var_1 - value_var_2)^2

A floating point error is generated when the difference is or becomes zero.

(value_var_1 - value_var_2) * (value_var_1 - value_var_2) does work without 
problems

Is this a known problem?

If I just create an static equation with 0^2 it does not generate the 
error, so it could be an underflow problem on the variables.
Is there a round or MIN function in the equation of TRNSYS?

Thanks

Henk WItte
