In my game I have an event that subtracts 0.03 from a global variable. I've done it by subtract 0.03 from variable, and add -0.03, and set variable to variable-0.03. Yet everytime it subtracts 0.0200000000000000006. The variable is at 0.33, and on the event that subtracts 0.03 from it sets the variable to 0.30000000000000004 rather than 0.3 I need it to be 0.3 because its supposed to trigger a specific event. Are there any ways to overcome this or round down to the nearest 0.01?
