Double Data Type

Holds double-precision 64-bit floating point numbers that can represent fractional values. It supports very large or very small numbers with decimal points.

The value range is approximately ±5.0 × 10⁻³²⁴ to ±1.7 × 10³⁰⁸.

Note: Because double uses floating-point representation, it can introduce rounding errors and may lack exact precision for certain decimal values.
