Integer vs floating-point (whole numbers vs decimal numbers) for Tech+
Short answer
Integer vs floating-point (whole numbers vs decimal numbers). Data types define what kind of data a variable can hold: - Integer: Whole number (no fractional part). Can be positive, negative, or zero. Examples: -3, 0, 42. Use for counting, indexing. - Floating-Point (Float/Double): Number with fractional part (decimal point). Examples: 3.14, -0.001. Stored approximately with limited precision. Use for measurements, calculations. - Boolean: Logical value with only two possible values: true or false. Often result of comparisons. Used for conditions and flags. - Character: Single text character like 'A', 'x', '7'.

Integer vs floating-point (whole numbers vs decimal numbers)
Integer vs floating-point (whole numbers vs decimal numbers). Data types define what kind of data a variable can hold: - Integer: Whole number (no fractional part). Can be positive, negative, or zero. Examples: -3, 0, 42. Use for counting, indexing. - Floating-Point (Float/Double): Number with fractional part (decimal point). Examples: 3.14, -0.001. Stored approximately with limited precision. Use for measurements, calculations. - Boolean: Logical value with only two possible values: true or false. Often result of comparisons. Used for conditions and flags. - Character: Single text character like 'A', 'x', '7'. Stored as integer (ASCII/Unicode code). - String: Sequence of characters representing text. Example: "Hello, World!".

Concept 3
How to recognize it on Tech+
On FC0-U71, stay at beginner IT depth: identify when the question is asking about Integer vs floating-point (whole numbers vs decimal numbers), then choose the basic concept or support action that matches the situation. Do not jump into advanced vendor administration unless the prompt clearly gives that scope.
