I'm using a set of triggers right now to keep track of how much weight I'm carrying. Each time I pick up an item, it adds the weight of that to a variable that is displayed on my status bar. Everything works fine except for the coins. Here's what I have:

Variable

Name: bit_weight
Value: 0.01

The same goes for each other type of coin. Now, when I pick up money, I have the following expression to add the weight to my total:

#TRIGGER {You take * (%d) copper Bit*} {#var weight_carried %eval((%1*@bit_weight)+@weight_carried)

Looking at it, I know that it should work, but it doesn't. When I highlight each variable in the Settings Editor to find out their value, it lists @bit_weight as being 0.00999999977648258. Any thoughts on why?

0.00999999977648258 is the normalized value of 0.01, as provided by the %norm function.

Since your trigger is specific to copper bits, you could use a specific formula.
#TR {You take * (%d) copper Bit*} {#MATH weight_carried ((@weight_carried * 100) + %1);#VAR weight_carried %insert( ".", @weight_carried, %len( @weight_carried) - 1)}

NOTE: This formula will fail in the unlikely event that you ever have a total weight of less than 0.10.
