public static float fma (float a, float b, float c)

Returns the fused multiply add of the three arguments; that is, returns the exact product of the first two arguments summed with the third argument and then rounded once to the nearest ` float`. The rounding is done using the round to nearest even. In contrast, if ` a * b + c` is evaluated as a regular floating-point expression, two rounding errors are involved, the first for the multiply operation, the second for the addition operation.

Special cases:

• If any argument is NaN, the result is NaN.
• If one of the first two arguments is infinite and the other is zero, the result is NaN.
• If the exact product of the first two arguments is infinite (in other words, at least one of the arguments is infinite and the other is neither zero nor NaN) and the third argument is an infinity of the opposite sign, the result is NaN.

Note that ` fma(a, 1.0f, c)` returns the same result as (` a + c`). However, ` fma(a, b, +0.0f)` does not always return the same result as (` a * b`) since ` fma(-0.0f, +0.0f, +0.0f)` is ` +0.0f` while (` -0.0f * +0.0f`) is ` -0.0f`; ` fma(a, b, -0.0f)` is equivalent to (` a * b`) however.

Parameters:
 `a` a value `b` a value `c` a value

Returns:  (a × b + c) computed, as if with unlimited range and precision, and rounded once to the nearest ` float` value

Since:  9
