For students enrolled in CS Colloquium (CS 195):

  • If you’re in Section 1, we expect you to attend the event when it occurs (synchronously).
  • If you’re in Section 2, we hope to record the event and post it for you to watch asynchronously.

Converting Decimal Numbers to Binary: Reaching Gigabytes Per Second

Abstract

With disks and networks delivering gigabytes per second, reading decimal numbers within XML, JSON and CSV files becomes a bottleneck. We consider the problem of converting decimal numbers to the nearest floating binary value. We present a C++ implementation that is often 4 times faster than the standard C library on modern 64-bit systems (Intel, AMD, ARM and POWER9). Our work is available as open source software used by major systems such as Rust, Go, LLVM libc, GNU stdlib++ (GCC).
