Here is a simple version of what I have set up:

#MATH answer 5/2

This should set the variable @answer equal to 2.5. Instead it removes the decimal and rounds down, leaving the variable equaling 2 instead of 2.5.

Is there any other command, or any functions i can use, that will keep the decimal on the number? I know how to use the %format function to display
the decimals, but the problem is my variable never has a decimal because the #MATH command is automatically rounding down.

Thanks in advance for the help!

You can also use the %float function to make a number a float.

It's worth adding that I think 5/2 producing an integer result is standard [correct] in a number of languages. As eclpmb mentioned, using 5.0/2 tells zMud that you're looking for a Float rather than an Int, or using %float works too. But it's not uncommon that 5/2 = 2 really.

That's because you're doing the calculation as integer and turning the result into a float.

calc 5/2 does %float (5/2) - it works out the value in the brackets and then turns it into a float. You can't just wrap the expression in %float you need %float(5)/2

#al {calc} {#show %ansi( high, green)%1 %ansi( high, white)~= %eval( %subregex( "%1", "((?<!\.)\b[0-9]+(?!\.([0-9]+\b)?|\.[0-9]+\b))", "%float(%%1)"))}
