classify

IEEE 754 classification.

is_quiet_nan

Check if the value is a quiet NaN.

is_signaling_nan

Check if the value is a signaling NaN.

is_subnormal

Check if the value is subnormal (unpacks to Normal with biased_exp == 0 in the original encoding, but our unpack normalizes subnormals; detect via original exponent range).

neg

Negate: flip the sign bit.

scalbn

Scale by power of 2: a * 2^n. Does not raise INEXACT (unlike multiplication by 2^n).
