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 fractionsandR...

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 a value of both types. Anintegervalue can accept zero, positive and negative numbers within the range ±1.7976931348623157...
