A scalar is a variable that stores a single unit of data at a time. The data that will be stored by the scalar variable can be of the different type like string, character, floating point, a large group of strings or it can be a webpage and so on.
Name = Alex Roll number = 13 Percentage = 87.65
Numeric scalar variables hold values like whole numbers, integers(positive and negative), float(containing decimal point). The following example demonstrates different types of numerical scalar variables in perl.
Positive Integer = 25 Negative Integer = -73 Floating Point = 23.5 Hexadecimal Form = 205
String scalar variables hold values like a word(made of different characters), a group of words or a paragraph. The following example demonstrates different types of string scalar variables.
String with alphabets = GeeksforGeeks String with numeric values = 17 String with alphanumeric values = gfg21 String within Single quotes = Hello Geeks String with special characters = ^gfg
