quaeratin/src/double-expansion/e-mult-by-2.ts

An extended precision floating point library (as per Shewchuk) - precision only limited by overflow / underflow

/**
 * Returns the result of multiplying a floating point expansion by 2.
 * * **error free**
 * * see [Shewchuk](https://people.eecs.berkeley.edu/~jrs/papers/robustr.pdf)
 * 
 * @param e a floating point expansion

    }
