Instance Method Details

#apply(operand) ⇒ RDF::Literal

Returns the smallest (closest to negative infinity) number with no fractional part that is not less than the value of arg. An error is raised if arg is not a numeric value.

Parameters:

• operand (RDF::Literal) —

  the operand

Returns:

• (RDF::Literal) —

  literal of same type

Raises:

• (TypeError) —

  if the operand is not a numeric value
