`pdfSetFloatPrecision`

Set the number of decimal digits used when formatting

BOOL32 __stdcall pdfSetFloatPrecision(PPDF IPDF, uint32_t NumTextDecDigits, uint32_t NumVectDecDigits);

Delphi

function pdfSetFloatPrecision(const IPDF: PPDF; NumTextDecDigits, NumVectDecDigits: Cardinal): LongBool; stdcall;

Purpose. Set the number of decimal digits used when formatting floating-point coordinates in the output content stream — separately for text-positioning numbers vs. vector/path-geometry numbers.

Description. Verified write-only no-op. Only NumTextDecDigits is even stored (into FFloatPrecision) — NumVectDecDigits is accepted by the ABI but never passed through at all, and FFloatPrecision itself has no getter exposed in this ABI and, more importantly, no read-site anywhere in the content- stream number-formatting code — the serializer always uses its own fixed internal precision regardless of this call. Calling this has no effect on output number formatting whatsoever.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`NumTextDecDigits`	Stored but never consulted.
`NumVectDecDigits`	Accepted but not even stored — dropped entirely.

Return value. True if IPDF is valid.
