These instructions return the larger or smaller of their operands. They differ These instructions return the larger or smaller of their operands. Note that
in their handling of quiet NaN inputs. Note that signaling NaN operands always unlike the IEEE 754-2008 `minNum` and `maxNum` operations, these instructions
cause a NaN result. return NaN when either input is NaN.
When comparing zeroes, these instructions behave as if :math:`-0.0 < 0.0`. When comparing zeroes, these instructions behave as if :math:`-0.0 < 0.0`.
