This is a fairly long description, but don’t get scared away. Some of it is just the expected output of the program that we’ll build here. We’ll start by getting two numbers from the user and storing them in Python variables while remembering to…
This topic contains information on handling numeric data type values and provides examples in the following sections: Basics Numeric values can be of integer and floating-point types. The TestComplete scripting engine does not distinguish floating-point and integer data types, so a variable can have...
Using isnumeric() method to check if the input is a numerical value Theisnumeric()method just like theisdigit()method, returnsTruefor a numerical value andFalsefor non-numerical values. However, thekey differencebetween both the method is that,isnumeric()method returnsTrueforunicode fractionsand...
