Whats the deal with decimals.

[Syp3r]

Could someone please explain how I can get MMF2 to correctly calculate equations with decimals in them?

Im thinking of using LUA to calculate instead, any examples for simply calculating somthing in that?

Thnx.

Don't know about Lua, but for MMF to calculate with decimals you have to tell it to calculate with floating points instead of integers.

Example:
8 / 5 will produce 1
8.0 / 5 will produce 1.6

But I need to divide "Named Varibles" with each other.

[Popcorn]

(Named Variable +0.0) / (Another Named Variable)

What Popcorn said.

Nope it aint working, this is what im trying to do.

(((( 2 * NAMEDVAR ) + NAMEDVAR + ( NAMEDVAR / 4 )) * NAMEDVAR / 100 ) + 5 ) * NAMEDVAR

NAMEDVAR = NamedVarible(value) it is not a decimal value.

-Ive tryed adding a .0 to the end of every number - doesnt work.

-Tryed replacing NAMEDVAR with (NAMEDVAR + 0.0) - doesnt work.

-Replaced NAMEDVAR with (0.0 + NAMEDVAR) -doesnt work.

-Have tryed different combinations of the above to get it working - doesnt work.


Maybe someone could make an example on how to do that in LUA, I assume LUA knows what math is.

if NAMEDVAR is one variable as opposed to lots then you can simplyfy the formula down to:

x(0.0325x²+5)

if you want to use lua the use the following...

(run script
"x=VARIABLE ; y=((0.0325*math.pow(x,2))+5)*x"

alternatley you use "a" to(number of named variables) as values instead of "x"

then retrive the public variable y (as value)

I just did a quick test, and it seems that the Named Variable object is unable to store floats (it floors them)

So I guess your problem is that you're trying to store the result in a named variable, meaning that even though the calculation is working correctly, when the result is stored it is rounded.

Using lua will not help that. You'll have to find a different way to store the resulting value. It might also be a good idea to contact the extension creator to see if float support can be added.

Try Xinok's Store Float extension. It "converts between the floating point and long data types for storage purposes".
