Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_54787 ( "Type" text, "Sign" real, "Exponent" real, "Significand" real, "Total bits" real, "Exponent bias" real, "Bits precision" real, "Number of decimal digits" text )

### Question ###
What's the sum of significand with ~34.0 decimal digits and an exponent bias larger than 16383?

### Accurate SQL ###

SELECT SUM("Significand") FROM table_54787 WHERE "Number of decimal digits" = '~34.0' AND "Exponent bias" > '16383'
