Description

Enumerates the FPU's floating-point rounding modes.

On 32-bit platforms, the FPU (Floating Point Unit) handles floating-point calculations. GetFPURoundMode is used to read, and SetFPURoundMode is used to set the FPU's rounding mode.

TFPURoundingMode can be one of the following values defined by TRoundingMode.

Value	Meaning
rmNearest	Rounds to the closest integer value.
rmDown	Rounds toward negative infinity.
rmUp	Rounds toward positive infinity.
rmTruncate	Truncates the value, rounding positive numbers down and negative numbers up.
