Abstract

This chapter studies the possible optimizations that arise in the specialization or fusion of floating-point operators. It builds upon the specialized fixed operators of previous chapters and focuses on exponent management and rounding issues specific to floating point.

Notes

  1. 1.

    Strictly speaking, as the exponent is constant, the point does not actually float here.

  2. 2.

    Of course, trusting the compiler to respect language standards is necessary but not sufficient to ensure safe applications.
