Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Search for | Example | Results |
---|---|---|
A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Search for | Operator | Example |
---|---|---|
Two or more words in the same topic |
|
|
Either word in a topic |
|
|
Topics that do not contain a specific word or phrase |
|
|
Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
A combination of search types | ( ) parentheses |
|
Data type: Number
The number data type is a primitive data type represented by the number 1 in the database dictionary. A number indicates an amount and can be either a whole number, a positive or negative number, or a floating point number. Enter numbers with an optional sign (+ or -) followed by digits which are optionally followed by a decimal point, then more digits which are optionally followed by the letter E and an exponent.
The following number formats display valid numbers accepted by RAD.
Description | Valid literal examples |
---|---|
Integer | 1 |
Negative Integer | -1 |
Fixed Point | 32.1 |
Floating Point | 1.257E05 |
Furthermore, each bullet shows different representations of the same number:
- 1 = 1.0 = 1E0 = 1.0E0
- -1 = -1.0 = -1E0 = -1.0E0
- 32.1 = 32.10 = 3.21E1
- -32.1 = -32.10 = -3.21E1
- 1.257E05 = 125700 = 1.25700E5
