Here is the table of currently supported calls in CubePL:
| Operation | Explanation |
| 123.34 | a numerical constant |
| "STRING" | a string constant |
| -x | negative value of x |
| () | grouping (priority) |
| | | | absolute value |
| + - / * | arithmetical operations |
| A^x | A in power of x |
| > < >= <= != == | numerical comparison
|
| and or xor not | boolean operations |
| eq | string comparison |
| seq | case insensitive string comparison |
| =~ /expression/ | matching of regular expression |
| sin(x) cos(x) asin(x) acos(x) tan(x) cot(x) atan(x) acot(x) | trigonometrical functions |
| ln(x) | natural logarithm of x |
| exp(x) | natural exponent of x |
| sqrt(x) | square root value of x |
| random(x) | random number from 0 to x |
| pos(x) | returns x, if x>, or 0 |
| neg(x) | returns x, if x<0, or 0 |
| sgn(x) | returns -1, if x<0, 0 if x is 0 and 1 is x>0 |
| abs(x) | returns absolut value |
| ceil(x) | returns smallest integer value, which is bigger than x |
| floor(x) | returns biggest integer value, which is smaller than x |
| min(x,y) | returns smaller value of x and y |
| max(x,y) | returns bigger value of x and y |
| uppercase(x) | returns uppercase version of x |
| lowercase(x) | returns lowercase version of x |
| env("x") | returns a value of the environment variable x |
| local(var) | Declares (to compile time) a variable var as local. It cannot be redeclared later |
| global(var) | Declares (to compile time) a variable var as global. It cannot be redeclared later |
| ${var} | 0th element of the variable with name var |
| ${var}[x] | x-th element of the variable with name var |
| sizeof(var) | number of elements in the variable var |
| defined(var) | returns true (1), if the variable var is defined, otherwise it returns false (0) |
| metric::[uniq_name](i|e|*, i|e|*) | context sensetive value of metric uniq_name |
| metric::context::[uniq_name](i|e|*, i|e|*) | context sensetive value of metric uniq_name |
| metric::fixed::[uniq_name](i|e|*, i|e|*) | context independend value of metric uniq_name |
| metric::call::[uniq_name](c_id, i|e|*, s_id, i|e|*) | value of metric uniq_name for the call path with id c_id and system resource with an id s_id |
| cube::metric::set::[uniq_name]("X", "Y") | sets a property X of a metric uniq_name to value Y. Corrently supported are only "value" with value "VOID" or else |
| cube::metric::get::[uniq_name]("X") | returns a property X of a metric uniq_name. Corrently supported are
-
unique name - returns unique name of a metric uniq_name
-
display name - returns display name of a metric uniq_name
-
uom - returns unit of measurement of a metric uniq_name
-
dtype - returns data type of a metric uniq_name as a string
-
url - returns url of online help for the metric uniq_name
-
description - returns description of a metric uniq_name
-
value - returns property "value" for the metric uniq_name. Its value "VOID" deactivates metric and it returns always a zero.
