13. CUSTOM MACRO
S Also be aware of errors that can result from conditional expressions
using EQ, NE, GE, GT, LE, and LT.
IF[#1 EQ #2] is effected by errors in both #1 and #2, possibly resulting
in an incorrect decision.
Therefore, instead find the difference between the two variables with
Then, assume that the values of the two variables are equal when the
difference does not exceed an allowable limit (0.001 in this case).
S Also, be careful when rounding down a value.
When #2=#1*1000; is calculated where #1=0.002;, the resulting value
of variable #2 is not exactly 2 but 1.99999997.
Here, when #3=FIX[#2]; is specified, the resulting value of variable
#1 is not 2.0 but 1.0. In this case, round down the value after correcting
the error so that the result is greater than the expected number, or round
it off as follows:
When a divisor of zero is specified in a division or TAN, P/S alarm
No. 112 occurs.
