Convert float -> char*

[ern]

Anybody know the Linux equivalent (or even better some C standard
equivalent) for _gcvt() ? I want my float to become a char*. Thanks!

The standard way is to use sprintf() or, likely better, snprintf()
(standard in C99).

BTW - have you read the FAQ?

HTH,

Yes I know, but I've tried for a few hours now and I can't find what
I'm looking for.

Thanks, finally got something that worked here:

http://www.cplusplus.com/ref/cstdio/sprintf.html

float value = 0.2623452345
char sValue[50];
sprintf(sValue,"%.7f",value);
printf("string version is %s\n",sValue);

You tried for 2 hours to type in "comp.lang.c FAQ" and failed?
You might want to try something other than programming as a
career.

Not that hard, is it?

Remarkable.

Google "C FAQ"; it's the first hit.
