Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge
JavaScript has one numeric data type for all real numbers, whether integers or decimals.
This type is simply called:
Number
It follows the IEEE 754 double-precision floating-point standard internally,
but JavaScript does not expose separate types like float, double, or decimal.
Therefore:
It is not Float JavaScript does not have float primitives.
It is not Double this refers to the underlying IEEE 754 representation, but JavaScript's type is still just ''Number.''
It is not Decimal JavaScript has no built-in decimal type.
The correct answer is Number.
