-.TH Tcl_PrintDouble 3 8.0 Tcl "Tcl Library Procedures"
-.so man.macros
-.BS
-.SH NAME
-Tcl_PrintDouble \- Convert floating value to string
-.SH SYNOPSIS
-.nf
-\fB#include <tcl.h>\fR
-.sp
-\fBTcl_PrintDouble\fR(\fIinterp, value, dst\fR)
-.SH ARGUMENTS
-.AS Tcl_Interp *interp out
-.AP Tcl_Interp *interp in
-Before Tcl 8.0, the \fBtcl_precision\fR variable in this interpreter
-controlled the conversion. As of Tcl 8.0, this argument is ignored and
-the conversion is controlled by the \fBtcl_precision\fR variable
-that is now shared by all interpreters.
-.AP double value in
-Floating-point value to be converted.
-.AP char *dst out
-Where to store the string representing \fIvalue\fR. Must have at
-least \fBTCL_DOUBLE_SPACE\fR characters of storage.
-.BE
-.SH DESCRIPTION
-.PP
-\fBTcl_PrintDouble\fR generates a string that represents the value
-of \fIvalue\fR and stores it in memory at the location given by
-\fIdst\fR. It uses \fB%g\fR format to generate the string, with one
-special twist: the string is guaranteed to contain either a
-.QW .
-or an
-.QW e
-so that it does not look like an integer. Where \fB%g\fR would
-generate an integer with no decimal point, \fBTcl_PrintDouble\fR adds
-.QW .0 .
-.PP
-If the \fBtcl_precision\fR value is non-zero, the result will have
-precisely that many digits of significance. If the value is zero
-(the default), the result will have the fewest digits needed to
-represent the number in such a way that \fBTcl_NewDoubleObj\fR
-will generate the same number when presented with the given string.
-IEEE semantics of rounding to even apply to the conversion.
