1. numbers to text
I have a sequence of many floating point numbers.
I would like to check the length of each of them using getTextExtent() but text
data is required by this function and I am getting a
type check error when I use sequence[n].
If I include the variable assigned to sequence[n] in quotation marks it will
print the name of the variable.. How do I change the
value of the variable into text notation. ie what's the Euphoria equivalent of
the basic STR$() function.
I've read the sequence doc. and the examples for string literals are there but I
can't find anything for string variables.Thanks in
advance.
Regards
Bob

I think what you want is the sprint() function in misc.e
example:
include misc.e
atom num
sequence text
num = 15.1976
text = sprint (num) -- text is now "15.1976"
? length (text) -- will print 7
later,

-- see sprintf
object x x = {1234356.7890, 3.1415, 2}
for i = 1 to length(x) do -- convert numbers to strings "in place"
x[i] = sprintf("%g",x[i]) -- replace the %g with %8.2f or whatever format u like
end for
? length(x[2]) puts(1, x[2])
