Theint()orfloat()method is used to convert any input string to a number. We can use this function to check if the user input is a valid number. If the user input is successfully converted to a number usingint()orfloat(), it will be considered as a numeric value, if not it's a ...
Certain frameworks might have non-Number numeric implementation, in which case this approach will falsely return False. Using a try-except block Another method to check if a variable is a number is using a try-except block. In the try block, we cast the given variable to an int or float...
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...
