VEX : How to convert a float into a string

[sanostol]

I must be blind, I can not find that function, that convert a float into a string

You can use sprintf.

thank You

[sebkaine]

well sprintf doens't look to work for me 

string s = sprintf(f@class);

return an error !

Is there any alternative to Convert a float value to a string value 

Thanks !

[rich_lord]

You'd use sprintf like this in this situation (i think..).

string s = sprintf("%g",f@class);

Thanks Richard , it work !

Question: We have atoi() and itoa() where you can convert a string to integer/vice versa. And then we have atof() which converts a string to float - but no equivalent for the other way around. Am I missing something or does it simply not exist?

[sebkaine]

That look correct to me David, you have atof() but not the reverse function so you have to use the hack synthax describe by Richard to emulate ftoa()

[pezetko]

string ftoa(float in){
    return sprintf("%g", in);
}

s@str = ftoa(f@a);

Thanks Petr !

but that would also be logical to have ftoa natively !

well, sprintf() can do more to floats than just "convert", (maybe that is the reason plain ftoa() doesn't exist?)

you can specify the padding and number of decimal points it will round to, like: sprintf("%08.3f", value);

unfortunately, when I just tried it seems to be broken for some reason

Maybe it worked several years ago, but not now. Broken for a while.
