• Subset/SuperSet

  • A contained in B
    • A is subset B
    • B is superset of A

• 3e+3 = 3 * 10^+3 = 3000

• 3e-3 = 3 _ 10^-3 = 3 _ 1/10^3 = 0.003

• math is elegate precision instead of sharp

Percentage

calculate relative change(From - To)

((To - From) / From)

With a value "from" of 5.7s and "to" of 2.1s

2.1 - 5.7 = -3.6
3.6 / 5.7 = -0.63157895
# format to percent
0.63157895 * 100 = -63.157895 %

Rounding to two decimal places would yield a decrease in the speed index of 63.16%.
