`std.math.hardware.FloatingPointControl.rounding` - multiple declarations

Function FloatingPointControl.rounding

Change the floating-point hardware rounding mode


						
				void rounding
				(
				

				  uint newMode
				

				) nothrow @property @nogc @trusted;

Changing the rounding mode in the middle of a function can interfere with optimizations of floating point expressions, as the optimizer assumes that the rounding mode does not change. It is best to change the rounding mode only at the beginning of the function, and keep it until the function returns. It is also best to add the line:

pragma(inline, false);

as the first line of the function so it will not get inlined.

Parameters

Name	Description
newMode	the new rounding mode

Function FloatingPointControl.rounding


						
				static uint rounding() pure nothrow @property @nogc @trusted;

Returns

the currently active rounding mode
