float2string

float2string

[Pedro Jose Garcia Gil]

Hello.
I want to send a float by the serial port.

In C, I use the function "buffer=fcvt(source,7,&decimal,&signo);". I have
tried to import this function from C to Ada95, but I have had problems with
the char pointer (char *buffer). I don't know how to manage with the
equivalent in Ada to a char pointer.

Can I convert a float to a string in Ada?. How?.

 Thank you very much.

 Pedro.

You can use the attribute function Float'Image (<float-expression>) to
obtain a
scientific notation string.

If you want a particular format, you can use the Put procedure described in
the LRM A.10.9 (30)
