Simple division

[littlepinkpie]

Hi,

this is an easy question for someone with average knowledge of scripting.

Im making a simple division

float Division=9/2;
llOwnerSay((string)Division);

Im getting back 4.000000 instead of 4.5.

What am I doing wrong?

You are dividing two integers, which returns an integer.   You are then casting that integer as a float.

Try  float Division = 9.0/2.0;

 

[Parhelion Palou]

By using 9 and 2 rather than 9.0 and 2.0, you're using integers rather than floats. The system is doing an integer divide of 9/2, which is equal to 4, then casting it to a float: 4.00000

Pretty close to simultaneous with Innula

Match!

I have a dynamic list and I need to divide its length with an integer

Currently the list length is 9 and my integer is 2

So Im using

float Result;

MyList=llGetListLength(List);
Result=float(MyList)/float(MyInteger);
llOwnerSay((string)Result);

where MyList=9 and MyInteger=2
but Im getting syntax error at Result=

Bad syntax.  It should be

float Result = (float)MyList / (float) MyInteger;

[littlepinkpie]

Im declaring it: float Result;

[Rolig Loon]

As you should, assuming that you intend it to be a global float.

But still it says "Syntax error"

[Madelaine McMasters]

When you want the compiler to temporarily treat one kind of variable as another, you use a "typecast". Typecasts are always enclosed in parentheses. So, if you want to temporarily express the integer variable "MyList" as a float, you write "(float)MyList". You wrote float(MyList), which the compiler interprets as a function call to the routine "float" with the argument "MyList". There is no such function, and so you get a syntax error. The correct way to write it is as Rolig showed. "(float)MyList/(float)MyInteger".

Then you must have another error somewhere else in the script.

Or, read Maddy's note. ^^
