Decimaldel is a term used in numerical data processing to describe an operation that deletes or suppresses the fractional part of a decimal number. In its core form, decimaldel(x) yields the integer part of x by truncating toward zero, effectively discarding any digits after the decimal point.
With an optional parameter p, decimaldel(x, p) keeps at most p digits after the decimal point and

Applications of decimaldel include numeric data normalization, currency or display formatting where the fractional part is
