Method: OraNumber#round

Defined in:

ext/oci8/ocinumber.c

#round ⇒ Integer #round(decplace) ⇒ OraNumber

Overloads:

• #round ⇒ Integer

  Rounds self to the nearest Integer.

  Examples:

  OraNumber(1.49).round     # => 1
  OraNumber(1.5).round      # => 2
  OraNumber(-1.49).round    # => -1
  OraNumber(-1.5).round     # => -2

  Returns:

  • (Integer)
• #round(decplace) ⇒ OraNumber

  Rounds onum to a specified decimal place decplace.

  Examples:

  OraNumber(123.456).round(2)   # => #<OraNumber:123.46>
  OraNumber(123.456).round(1)   # => #<OraNumber:123.5>
  OraNumber(123.456).round(0)   # => #<OraNumber:123>
  OraNumber(123.456).round(-1)  # => #<OraNumber:120>

  Parameters:

  • decplace (Integer)

  Returns:

  • (OraNumber)
