	3
Dest	N7:12
	-3

Negate

NEG

When the input conditions are true, take the opposite sign of the Source (N7:3) and store the result in the Destination (N7:12). This instruction turns positive values into negative values and negative values into positive values.

Csets if the operation generates a carry; otherwise resets

Vsets if overflow is generated; otherwise resets

Zsets if the result is zero; otherwise resets

Ssets if the result is negative; otherwise resets

SIN

SINE

Source F8:11

Sine

SIN

When input conditions go true, take the sine of the value in F8:11 and store the result in F8:12.
