ALL Abbreviation types use the decimal places Abbreviation v1 : Just changes the decimal places of the number Abbreviation v2 : Changes the number to the Basic notation - for example 1.5K, the time it starts can be changed!! Abbreviation v3 : Changes the number to the e notation - for example 1.5e3, the time it starts can be changed!! Abbreviation v4 : Changes the number to the Basic notation as well as the e notation, the timing of both of these can be changed, except when equal will use v1... - for example 1.5K for basic and 1.5e3 for e... This is all the Abbreviation types that I know of, I may find more!!
Put the number you want to abbreviate and it will replace the variable "Return" with the abbreviated version, make sure to display text with the return variable or make a new variable that has the abbreviation in it making that one show and make sure not to use the set or change variable block with this display, the number that can be changed and set will be hidden.
