How to round a number to the third decimal place?

That’s really nice. But you don’t need to loop a multiplication. That’s what the power operator is for.

These lines:

@annwu23

*temp ten_power 1
*temp times 0
*label multiplication
*set ten_power * 10
*set times + 1
*if (times < digits)
    *goto multiplication
*set {varname} * ten_power

Can become:

*set {varname} * (10 ^ digits)
