6.3.2 Variable Typing and Comparison Expressions ¶

The Guide is definitive. Reality is frequently inaccurate.

Unlike in other programming languages, in awk variables do not have a fixed type. Instead, they can be either a number or a string, depending upon the value that is assigned to them. We look now at how variables are typed, and how awk compares variables.

• String Type versus Numeric Type
• Comparison Operators
• String Comparison Based on Locale Collating Order
