Math operations
Warning
For Engine versions older than v1.7.0, only a subset of the below operations are supported.
Multiple fields in the gridmo webapp support mathematical operations, which are resolved by the gridmo engine. These operations allow you to perform calculations directly within supported fields, enhancing flexibility in commands, tables, and analysis records.
Supported Operations
You can use the following mathematical operators and functions:
- Basic arithmetic:
+,-,/,* - Brackets:
()for grouping expressions
Additional functions are available:
| Function | Example |
|---|---|
| Absolute value | abs({{i_p_poc}}) |
| Square root | sqrt({{i_p_poc}}) |
| Trigonometric functions | sin({{i_angle}}), cos({{i_angle}}), tan({{i_angle}}) |
| Inverse trigonometric functions | asin({{i_value}}), acos({{i_value}}), atan({{i_value}}) |
| Logarithmic functions | log({{i_p_poc}}), log10({{i_p_poc}}) |
| Degrees to radians | deg2rad({{i_angle}}) |
| Radians to degrees | rad2deg({{i_angle}}) |
| Exponentiation | {{i_p_poc}}**2 |
| Sign (-1 if negative, 1 if positive, 0 if 0) | sign({{i_p_poc}}) |
| Mathematical constants | pi |
tip
In gridmo's online documentation, Arguments marked with the number emoji (🔢) support the above math operations and functions.
