##### Number Providers

Number provider types and values have been split into two separate registries: minecraft:context_int_provider and minecraft:context_float_provider to avoid accidental loss of precision and range due to mixing of float and integer operations

Note: those new types should not be confused with already existing minecraft:int_provider_type and minecraft:float_provider_type , which are context-free providers, used mostly for world generation

Following number provider types have been split into integer and float variants:

- minecraft:weighted_list

- minecraft:conditional

- minecraft:number_dispatcher

- minecraft:environment_attribute

Following number providers types are now only available in integer variant:

- minecraft:binomial

- minecraft:score

Following number providers types are now only available in float variant:
