Oracle Message PLS-01907 - : number precision too large

ERROR: number precision too large
CAUSEThe number begin copied or assigned had too many digits to the left of the decimal and did not fit into its destination. In other words, there is a number precision mismatch. This error may also occur if, for example, an attempt is made to assign a character string to a number, as demonstrated below. a varchar2(4); b number(1,1); a : = 10.1; b : = a;
ACTIONFirst, check explicit number precision value mismatches. If none are found, then consider implicit conversions of other types to numbers, including conversions performed during binds.
