CIMPLICITYSupported Operations for point_expression Field
The point_expression field supports the following operations:
| Arithmetic | +, -, /, *, ), (. | Include any point types except Boolean and floating point. |
| Logical | AND, OR, XOR, NOT. | Can include only Boolean points types. |
| Bitwise | BAND, BXOR, BNOT. | Can contain only Boolean and integer point types. |
| Relational | LT, GT, EQ, LE, NE, GE. | |
| Functions |
ALARM(), A2(), WARNING(), A1(), ALARM_HI(), AH2(), ALARM_LO(), AL2() WARNING_HI(), AH1(), WARNING_LO(), AL1(), and AL()
