int versus float (sum) (v4)

Revision 4 of this benchmark created by electricessence on

Description

Let's compare apples to apples.

We will use the for loop itself as the arithmetic mechanism.

Need to be sure types are kept consistent.

Setup

var
      int_0 = 0 | 0,
      max = 10000,
      maxInt = max | 0,
      maxFloat = 1
      incrementInt = 1 | 0,
      incrementFloat = 1/max;
    
    var resultInt = int_0, resultFloat = 0;

Teardown


    resultInt = int_0;
    resultFloat = 0;

Test runner

Ready to run.
