In C/C++ the possibility exists to write to a string.
Is there something like that in ADA?
I want to write several floating and fixed point parameters to a string with
each a dedicated but different number of digits behind the decimal point.
for instance a= 4.10 b= 5.2 c=7.123
In C/C++ it can be done by sprintf("a= %.2f b=%.1f c=%.3f",a,b,c);
I have seen that in Ada writing to a file or a device it can also be done
with the PUT precedure from Text-IO but I cannot find the way to use PUT for
outputing to a string.
I possibility that crossed my mind is using the Fixed point types but
converting the floating point values to fixed point values in a way that I
can use a temporary type declared like:
type number is delta fix_p(after) range <>;
where fix_p is an array (0.1, 0.01, 0.001) and after is 1, 2 or 3 doesnot
seem to work because fix_p(after) is not static.
How can I reach my objective or should I completely write it myself?
