NAME

VarUI8FromDec (OLEAUT32.441)

SYNOPSIS

HRESULT VarUI8FromDec
 (
  DECIMAL* pdecIn,
  ULONG64* pui64Out
 )

DESCRIPTION

Convert a VT_DECIMAL to a VT_UI8.

PARAMS

pDecIn [In] Source.

pui64Out [Out] Destination.

RETURNS

Success: S_OK.

Failure: E_INVALIDARG, if the source value is invalid DISP_E_OVERFLOW, if the value will not fit in the destination.

NOTES

Under native Win32, if the source value has a scale of 0, its sign is ignored, i.e. this function takes the absolute value rather than fail with DISP_E_OVERFLOW. This bug has been fixed in Wine's implementation (use VarAbs(3w) on pDecIn first if you really want this behaviour).

IMPLEMENTATION

Defined in "oleauto.h".

Implemented in "dlls/oleaut32/vartype.c".

Debug channel "variant".
