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 it is possible to decrease the accuracy of the delivered values.
