Remarks
This function sets the precision - number of digits to the right of the
decimal - when double floating-point values are transmitted. The TPS'
system software always calculates with highest possible precision. The
default precision is fifteen digits. However, if this precision is not needed
then transmission of double data (ASCII transmission) can be speeded up
by choosing a lower precision. Especially when many double values are
transmitted this may enhance the operational speed. The usage of this
function is only meaningful if the communication is set to ASCII
transmission mode. In the case of an ASCII request, the precision of the
server side will be set. Notice that trailing Zeros will not be sent by the
server and values may be rounded. E.g. if precision is set to 3 and the exact
value is 1.99975 the resulting value will be 2.0
Note: With this function one can decrease the accuracy of the delivered
values.
