Automatic Decimal Point
P480.06
Sets the number of decimal places to automatic.
P481 thru P489
Sets the significant digits to the right of the decimal point
for Variables #1 thru #9, the same as parameter P480.
14.11 Rounding (VARS and REGS)
(VARS)
Several factors are considered when rounding a VAR. A
VAR rounds internally to an accuracy of 1 part in
3,000,000. The "500 series Simulator" software will
have a greater accuracy. The range of a VAR is +/-1 x
10
38
. Rounding occurs only when the entered value
exceeds six significant digits on the display. The 574
analyzes the entered value and determines the best way
this value will be represented on the six digit display.
The displayed value will be rounded up or down
accordingly and will eliminate any trailing zeros. The
internal value will remain intact up to the stated accuracy
of 1 part in 3,000,000. A VAR will print the value
exactly the way its represented on the display with the
exception of the decimal point. If there are no significant
digits to the right of the decimal point, the decimal point
will not print out.
ie. 123.9997 entered
124. displayed
124 printed
Note: If the VAR is set for a fixed decimal point
(P480-P489) then all digits including zeros to the right of
the decimal point will be transmitted.
ie. 123.9997 entered
124.00 displayed
124.00 printed
Rounding will occur on a value entered into a VAR if the
entry has a greater number of digits to the right of the
decimal point. A VAR will either round up or down and
is dependant on the number of decimal places selected.
ie. Setting of 3 decimal places.
1) 10.0005 entered
10.000 displayed
10.000 printed
2) 10.00051 entered
10.001 displayed
10.001 printed
ie. Setting of 2 decimal places.
(dollars and cents)
5.1 entered
5.10 displayed
5.10 printed
(REGS)
A REG retains "whole" numbers only. Any fractional
portion of a number entered will round up or down to the
nearest whole number. The accuracy of a REG is 1 part
in 3,000,000. The full range is +/-1 x 10
38
.
ie. 20.4 entered
20 displayed
20 printed
20.5 entered
21 displayed
21 printed
-100.55 entered
-101 displayed
-101 printed
14.12 Exponential Numbers (VARS)
Very Large Numbers
The VARS will retain very large numbers. A value
entered that is greater than 999999 will be represented on
the display in exponential form (Scientific Notation).
The value will however print out in full decimal form,
rounded to an accuracy of 1 part in 3,000,000.
ie.
1) 1000000 entered
1.Exp6 displayed
1000000 printed
