How to change fixnum type into a string type

First of all, 100.00 is not a fixnum, it's a flonum. A fixnum is an integer.

The easiest is to use sprintf though. Either use:

myreal=100.0
myint=100

sprintf(str "%d" myint) => "100"
sprintf(str "%g" myreal) => "100"
sprintf(str "%.2f" myreal) => "100.00"

If you're only interested in the return value, you can pass nil as the first argument rather than the variable name.

thank you very much！

And I still have some confusions ：

when I try to combine a flonum（100.00） and a string （“k”），I use the  function：strcat .

here are some procedure: 

sum=sum+value   ;;both sum and value are flonun type

mystring=strcat("sum" "k")   ;;;;the function does not work as I think.

the result  I  expect to see is :mystring="100.00k" 

would you plz help me ?

thanks 

It sounds as if it would be a very good idea for you to read the SKILL Language User Guide at <ICinstDir>/doc/sklanguser/sklanguser.pdf (can also be found in cdnshelp). I can't see why you would think that doing a strcat of two literal strings would do anything other than concatenate them together - so strcat("sum" "k") would clearly give "sumk" - since "sum" is in quotation marks, it's clearly a literal string, not a variable.

If you want to get this as a string, you can do:

sprintf(mystring "%.2fk" sum)

Or you could have done:

sprintf(sumAsString "%.2f" sum)
mystring=strcat(sumAsString "k")

And by the way, there's no tax on characters in this forum. English is my first language, so I rather like "please" being spelt correctly rather than an SMS-style abbreviation. It's one of those things I'm picky about, sorry...

 Hi,

You could use the function aelSuffixWithUnits() to take the value and the units and produce a formatted result, for example:

aelSuffixWithUnits("100.00" "k")
=> "100 k"

OR print it with formatting (in this case "print" it to a string variable):

sprintf(mystring "%g k" sum)
=> "100 k"

The benefit of the aelSuffixWithUnits() function is that it can accept a floating point number or a string for its input.  You can control the decimal places etc. by modifying the format specifier '%g'
