Number Format Models You can use number format models: In the TO_CHAR function to translate a value of NUMBER datatype to VARCHAR2 datatype In the TO_NUMBER function to translate a value of CHAR or VARCHAR2 datatype to NUMBER datatype All number format models cause the number to be rounded to the specified number of significant digits. If a value has more significant digits to the left of the decimal place than are specified in the format, pound signs (#) replace the value.
