Number of mantissa bits to take into account for hashing floats. This option is read-only for a trained model.
Parameters¶
return
int
Current mantissa_nbits
value.
newmantissa_nbits
int
New mantissa_nbits
value, should be non-negative and
less than or equal to 52
, that is a number of
mantissa bits in a C++ 64-bit double
.
except
