getMaxLength()

public long getMaxLength()

Optional. Maximum length of values of this field for STRINGS or BYTES.

getPrecision()

public long getPrecision()

Optional. Precision (maximum number of total digits in base 10) and scale (maximum number of digits in the fractional part in base 10) constraints for values of this field for NUMERIC or BIGNUMERIC.

It is invalid to set precision or scale if type is not "NUMERIC" or "BIGNUMERIC".

If precision and scale are not specified, no value range constraint is imposed on this field insofar as values are permitted by the type.

Values of this NUMERIC or BIGNUMERIC field must be in this range when:

  • Precision (P) and scale (S) are specified: [-10^(P-S) + 10^(-S), 10^(P-S) - 10^(-S)]
  • Precision (P) is specified but not scale (and thus scale is interpreted to be equal to zero): [-10^P + 1, 10^P - 1].

    Acceptable values for precision and scale if both are specified:

  • If type = "NUMERIC": 1 <= precision - scale <= 29 and 0 <= scale <= 9.

  • If type = "BIGNUMERIC": 1 <= precision - scale <= 38 and 0 <= scale <= 38.

    Acceptable values for precision if only precision is specified but not scale (and thus scale is interpreted to be equal to zero):

  • If type = "NUMERIC": 1 <= precision <= 29.

  • If type = "BIGNUMERIC": 1 <= precision <= 38.

    If scale is specified but not precision, then it is invalid.

int64 precision = 8 [(.google.api.field_behavior) = OPTIONAL];

Returns
TypeDescription
long

The precision.

getScale()

public long getScale()

Optional. See documentation for precision.

int64 scale = 9 [(.google.api.field_behavior) = OPTIONAL];

Returns
TypeDescription
long

The scale.
