Description
value

scale
Optional
Must be an integer literal between 0 and 28, inclusive. Specifies the number of digits allowed after the decimal point. If you omit this argument, the function returns a value with the same scale as the input value.

Return Value

Decimal of precision and scale between 0 and 28, inclusive.
NULL if a value passed to the function is NULL.
If the string contains a non-numeric character, converts the numeric portion of the string up to the first non-numeric character.
If the first numeric character is non-numeric, returns 0.
If the return value is Decimal with precision greater than 15, you can enable high precision to ensure decimal precision up to 28 digits.
