SQLSCHAR scale; SQLCHAR sign; SQLCHAR val[16]; } SQL_NUMERIC_STRUCT; Simplified, the design of a NUMERIC is a 128 bit integer value. Look at the number, remove the decimal (ignore it for the 128 bit integer view) and store it in the val member, keeping the...
Ifnis negative, thenROUND(n, integer) returns -ROUND(-n, integer). Ifnis positive, then ROUND(n, integer) = FLOOR(n * POWER(10, integer) + 0.5) * POWER(10, -integer) ROUNDapplied to aNUMBERvalue may give a slightly different result fromROUNDapplied to the same value expressed in fl...
