Light Sine??

I noticed in the debugger that Sine shows a lot of decimals, about 10 decimals.

is there a way to use only 1 or 2 decimals, thinking that that will be less CPU taxing?

thx

TL;DR: Is there a "Light Sine"?

round(N * 100) / 100

for 2 decimals

1000 for 3 decimals

etc...

depends on when you do the rounding though... if you do it after the calculation it wont help :-)

But if you round and then use the number it should help.

thanks a lot mr. elephant

What's the right way?

I tried this:

1.- Output to Value

2.- Set "every tick", set sprite's Angle using the round(sprite.sine.value) formula

is that correct?

It won't be less CPU taxing to display less decimals, it will just look neater.

It won't be less CPU taxing to display less decimals, it will just look neater.This.

Plus: the conversion uses processor time, adding to the load.

It's just us humans who need numbers to be displayed with as less digits as possible - as long as we are not talking about our income <img src="smileys/smiley36.gif" border="0" align="middle" />

Im trying to find a solution 'cause I'm experiencing high cpu usage, check this:

as I said. it wont help you if you do the rounding after the calculation. It can only help you in cases where you use the rounded value alot afterwards.

E.g.

This:

roundedValue = round(12.123132165468798763213654) --> (roundedvalue = 12.12)

for i = 0 to i = 1000000

Do calculations on roundedValue

Would be faster then this:

for i = 0 to i = 1000000

Do calculations on 12.123132165468798763213654

But in your case (as the others mention) you will just add an extra calculation to the cpu cycle (the rounding)
