FLOAT64_PRECISION

Effective number of bits in the significand of a double-precision floating-point number.

Installation

npm install @stdlib/constants-float64-precision

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch.
• If you are using Deno, visit the deno branch.
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch.
