What is the data type of pi?

A. Decimal
B. Float
C. Number
D. Double

정답：C

설명：
In JavaScript, there is only one numeric type for ordinary numbers: number.
* JavaScript number is a double-precision 64-bit binary format (IEEE 754).
* There is no separate float, double, or decimal type in core JavaScript.
So:
typeof pi === ' number ' ;
Hence, the correct answer is:
* A. Number
Options B, C, D are specific numeric types found in other languages (like C, Java, C#), not distinct types in JavaScript.
Study Guide Concepts:
* JavaScript primitive types
* typeof operator and number
* Lack of separate float / double / decimal types in JS
