fmaf

Computes x * y + z.

The result is rounded according to the rounding mode determined by the value of ROUNDS.

ROUNDS indicates the implementation-defined rounding behavior for floating-point addition, and has one of the following values:

• -1 The rounding mode is not determinable.
• 0 Rounding is towards 0.
• 1 Rounding is towards nearest number.
• 2 Rounding istowards positive infinity.
• 3 Rounding is towards negative infinity.
• Other values represent machine-dependent, non-standard rounding modes.

Parameters:

x	A numeric value.
y	A numeric value.
z	A numeric value.
