bigint_arithmetic

Multiplying numbers larger than what's possible with a normal 64 bit processor.

  • Baseline: Add 1 + 1
  • Fact50: Take the factorial of 50. (Gets up to 256 bits)
  • Fact95: Take the factorial of 95. (Gets up to 512 bits)

Note: We cannot include GMP or unstable crates. GMP can't be included because it is not crossplatform (not available in Windows).

baseline fact50 fact95
num_bigint 0.114 9.864 28.497
numext_fixed_uint 0.008 70.474 423.588
uint 0.016 116.127 902.055

Speed units are in microseconds per iteration. Less is better.
