+MLNumber is used when specifying the type of a numeric option for an {{MLOperand}} which can be of any {{MLOperandDataType}}, including both 64-bit integer types ({{MLOperandDataType/"uint64"}} and {{MLOperandDataType/"int64"}}) and 32-bit floating point ({{MLOperandDataType/"float32"}}). Implementations process the value according to the corresponding {{MLOperandDataType}}. For example, if {{MLGraphBuilder/clamp(input, options)}} is called with an {{MLOperand}} with [=MLOperand/dataType=] {{MLOperandDataType/"uint32"}}, the {{MLNumber}} parameters are explicitly [=cast=] to {{unsigned long}}.
+
+

+  Specifying the option as {{double}} would lose accuracy when passing values over 253, and specifying {{long long}} would disallow values over 263.
+

+
+Issue(whatwg/webidl#1388): Support for unions of {{bigint}} and [=numeric types=] new in [[WEBIDL]], and implementation support is also limited. Prototype implementations are encouraged to provide feedback for this approach.
