Is there a way to increase the number of digits displayed by a variable?
How many digits does the sine function output given a whole angle input?

Thanks, Chris

when gf clicked
clear
set [angle v] to 0
set [sine v] to 0
set [opposite v] to 0
hide
ask [What is the angle?] and wait
set [angle v] to (answer)
set [sprite3x v] to ([cos v] of ((angle) * (250)))

Fixing your scratchblocks.... please give a moment.
Assuming this is what you mean?

You've touched upon one of the "magical" issues with Scratch.
We don't have precision setting for numeric output.
We also cannot specify a location for output.
I've seen everything from 3 to 15 digit mantissas so there's some floating-point library fun behind the scenes and displayed variables have a tendency to stack in a column along the left-hand side of the screen even after they've been saved in other positions.
