The process involves internally converting the given item, along with an optional base, to an integer using Convert To Integer. The resulting integer is then converted to a binary string representation, using the base 2. The final output may include an optional prefix and can be required to have a minimum length, excluding the prefix and any minus sign. In case the resulting binary string is initially shorter than the required length, it is padded with zeros to meet the minimum length requirement.

To convert a number to binary in Robot Framework, you can use the Convert To Binary
keyword from the Binary
library. Here’s an example:
*** Settings ***
Library BuiltIn
*** Test Cases ***
Convert Number to Binary
${binary}= Convert To Binary 42
Should Be Equal As Strings ${binary} 101010
In this example, we import the B
uiltIn library using the Library
setting. We then call the Convert To Binary
keyword and pass the number we want to convert as an argument. The keyword returns a string containing the binary representation of the number.
Finally, we use the Should Be Equal As Strings
keyword to verify that the binary representation is correct.
Note that the Convert To Binary
keyword can also take an optional argument to specify the number of bits in the binary representation. For example:
*** Test Cases ***
Convert Number to Binary with Padding
${binary}= Convert To Binary 42 8
Should Be Equal As Strings ${binary} 00101010
In this example, we specify that the binary representation should have 8 bits, so the Convert To Binary
keyword pads the result with leading zeroes to ensure that the binary representation has the correct number of bits.
