.SH NAME
\fBVarNumFromParseNum\fR (OLEAUT32.47)
.SH SYNOPSIS
HRESULT VarNumFromParseNum
 (
  NUMPARSE* \fIpNumprs\fR,
  BYTE*     \fIrgbDig\fR,
  ULONG     \fIdwVtBits\fR,
  VARIANT*  \fIpVarDst\fR
 )

.SH DESCRIPTION
.PP
Convert a \fBNUMPARSE\fR structure into a numeric Variant type. 

.SH PARAMS
\fIpNumprs\fR \fB[In]\fR  Source for parsed number. cDig must be set to the size of \fIrgbDig\fR.
.PP
\fIrgbDig\fR \fB[In]\fR  Source for the numbers digits.
.PP
\fIdwVtBits\fR \fB[In]\fR  \fBVTBIT_\fR flags from \fB"oleauto.h"\fR indicating the acceptable dest types.
.PP
\fIpVarDst\fR \fB[Out]\fR  Destination for the converted Variant value.
.PP

.SH RETURNS
.PP
\fBSuccess:\fR \fBS_OK\fR. \fIpVarDst\fR contains the converted value. 
.PP
\fBFailure:\fR \fBE_INVALIDARG\fR, if any parameter is invalid. \fBDISP_E_OVERFLOW\fR, if the number is too big for the types set in \fIdwVtBits\fR. 

.SH NOTES
.PP
\fB-\fR The smallest favoured type present in \fIdwVtBits\fR that can represent the number in \fIpNumprs\fR without losing precision is used. 
.PP
\fB-\fR Signed types are preferred over unsigned types of the same size. 
.PP
\fB-\fR Preferred types in order are: integer, float, double, currency then decimal. 
.PP
\fB-\fR Rounding (dropping of decimal points) occurs without error. See \fBVarI8FromR8(3w)\fR for details of the rounding method. 
.PP
\fB-\fR \fIpVarDst\fR is not cleared before the result is stored in it. 
.PP
\fB-\fR WinXP and Win2003 support \fBVTBIT_I8\fR, \fBVTBIT_UI8\fR but that's buggy (by design?): If some other \fBVTBIT\fR's for integers are specified together with \fBVTBIT_I8\fR and the number will fit only in a \fBVT_I8\fR Windows(tm) will \fB"cast"\fR the number to the smallest requested integer truncating this way the number. Wine doesn't implement this \fB"feature"\fR (yet?). 

.SH IMPLEMENTATION
.PP
Declared in \fB"oleauto.h"\fR. 
.PP
Implemented in \fB"dlls/oleaut32/variant.c"\fR. 
.PP
Debug channel \fB"variant"\fR.
