| .SH NAME |
| ecvt_r, fcvt_r, qecvt_r, qfcvt_r \- convert a floating-point number to a string |
| .SH SYNOPSIS |
| .B #include <stdlib.h> |
| .sp |
| .BI "int ecvt_r(double " number ", int " ndigits ", int *" decpt , |
| .BI "int *" sign ", char *" buf ", size_t " len ); |
| .sp |
| .BI "int fcvt_r(double " number ", int " ndigits ", int *" decpt , |

| .sp |
| .BI "int qecvt_r(long double " number ", int " ndigits ", int *" decpt , |
| .BI "int *" sign ", char *" buf ", size_t " len ); |

| .SH DESCRIPTION |
| The functions |
| .BR ecvt_r (), |
| .BR fcvt_r (), |
| .BR qecvt_r () |
| and |
| .BR qfcvt_r () |
| are identical to |
| .BR ecvt , |
| .BR fcvt , |
| .BR qecvt |
| and |
| .BR qfcvt , |
| respectively, except that they do not return their result in a static |
| buffer, but instead use the supplied |
| .I buf |
| of size |
| .IR len . |
| See |
| .BR ecvt (3) |
| and |
| .BR qecvt (3). |
| .SH "RETURN VALUE" |
| These functions return 0 on success, and \-1 otherwise. |
| .SH NOTES |
| These functions are obsolete. Instead, |
| .BR sprintf () |
| is recommended. |
| .SH "CONFORMING TO" |
| These functions are GNU extensions. |
