What are data types? As you can guess by the name, data types describe the kind of data a variable can hold. For example, if the data type is Int32, then the variable must hold an integer. Likewise, if the data type is a String, then the variable must hold a text. Data types Listed below are some of the most commonly used ones. System.String System.String stores texts. This type of data comes with many methods of data manipulation that will be explained in detail in another lesson, namely Data Manipulation with Strings in Studio. Numeric(category) These variables store numbers. There are different sub-types of numerical variables. For example: Int32 - System.Int32 (signed integers): 10, 299, -100 Long - System.Int64 (long integers): 54354353430, -11332424D Double - System.Double (allows decimals, 15-16 digits precision): 19.1234567891011 System.Boolean stores one of two value: True or False Collection(category) Collec...
