Hello
I am trying to teach my daughter how to calculate Pi by calculating the area of a circle of radius 1, adding up surfaces of sections.
I need the sqrt function and I find that it always trims the number to the first digit after the comma.
is there a way to increase the accuracy of floating point variables and functions in scratch ?
thanks!

I can't reproduce this. What number is it trimming?

I think I might know the issue--output. The output trims it, but the roots themself are accurate. An example is my project, Computing Pi

(join (value) [ ])

This should prevent auto-rounding. smile

Sweet, some one actually looked at my floating point project, and shared the technique! Makes it all worth it.
