Expression
An expression is made up of the combination of variables/constants/literals and
operators/functions. The order of expressions can be changed by enclosing the
expression you wish to prioritize with parentheses. The order of precedence (the order
in which the operators are evaluated in a compound expression) is described later.
Variables
M:
Measured value
S:
Source value
T:
Time stamp equivalent to GMT in 1
µ
s resolution (unit is seconds)
M[n]: The current measured value to the measured value 15 measurements in the past
(before the computation) specified by n in the range of 0 to –15
S[n]: The current source value to the source value 15 source cycles in the past
specified by n in the range of 0 to –15
T[n]: The current time stamp to the time stamp 15 cycles in the past specified by n in
the range of 0 to –15
I:
Source value or measured value that is a current.
V:
Source value or measured value that is a voltage.
A:
Parameter A
B:
Parameter B
C:
Parameter C
X:
Internal variable X
Y:
Internal variable Y
Z:
Internal variable Z
J:
Counter Cleared to 0 when the statement for substituting initial values into
internal variables is executed and incremented for subsequent computations.
Constants
PI:
Ratio of the circumference
3.1415926...
E:
The base of the natural logarithm 2.7182818...
Literals
Integer, fixed-point real number, and floating-point real number
Example 1.0 0.1234 -1.2345E-1
