Source - atan2
- Quadrant-aware arctangent, including signed zeros and infinite operands.
- cos
- Scalar cosine using the common angle reduction.
- exp2
- Platform-independent base-two exponent; finite underflow rounds into subnormals.
- log2
- Binary logarithm using a normalized mantissa and a convergent atanh series.
- log10_round
- Nearest integer decimal logarithm; nonpositive inputs produce the SSE indefinite value.
- pow
- Effect power contract: y=0 yields 1, nonpositive bases yield 0, NaNs propagate canonically.
- rz_exp2
- Existing rotation/zoom base-two exponent API.
- rz_log2
- Existing rotation/zoom base-two logarithm API.
- scale
- Decimal scaling with the same 64-bit significand intermediate rounding as x87.
- scale_round
- Nearest-even integer after decimal scaling, including native indefinite overflow.
- sin
- Scalar sine using the common angle reduction.
- sincos
- Cosine and sine with shared quadrant reduction; return order matches the x87 API.
