Instance Method Details

#*(arg0) ⇒ BigDecimal #* ⇒ void

Performs multiplication:

4 * 2              # => 8
4 * -2             # => -8
-4 * 2             # => -8
4 * 2.0            # => 8.0
4 * Rational(1, 3) # => (4/3)
4 * Complex(2, 0)  # => (8+0i)

Overloads:

• #*(arg0) ⇒ BigDecimal

  Parameters:

  Returns:
• #* ⇒ void

  This method returns an undefined value.

def *: (BigDecimal) -> BigDecimal
| ...

#+(arg0) ⇒ BigDecimal #+ ⇒ void

Performs addition:

2 + 2              # => 4
-2 + 2             # => 0
-2 + -2            # => -4
2 + 2.0            # => 4.0
2 + Rational(2, 1) # => (4/1)
2 + Complex(2, 0)  # => (4+0i)

Overloads:

• #+(arg0) ⇒ BigDecimal

  Parameters:

  Returns:
• #+ ⇒ void

  This method returns an undefined value.

# File 'sig/big_decimal.rbs', line 1296

def +: (BigDecimal) -> BigDecimal
| ...

#-(arg0) ⇒ BigDecimal #- ⇒ void

Performs subtraction:

4 - 2              # => 2
-4 - 2             # => -6
-4 - -2            # => -2
4 - 2.0            # => 2.0
4 - Rational(2, 1) # => (2/1)
4 - Complex(2, 0)  # => (2+0i)

Overloads:

• #-(arg0) ⇒ BigDecimal

  Parameters:

  Returns:
• #- ⇒ void

  This method returns an undefined value.

# File 'sig/big_decimal.rbs', line 1312

def -: (BigDecimal) -> BigDecimal
| ...

#/(arg0) ⇒ BigDecimal #/ ⇒ void

Performs division; for integer numeric, truncates the result to an integer:

 4 / 3              # => 1
 4 / -3             # => -2
 -4 / 3             # => -2
 -4 / -3            # => 1

For other +numeric+, returns non-integer result:

 4 / 3.0            # => 1.3333333333333333
 4 / Rational(3, 1) # => (4/3)
 4 / Complex(3, 0)  # => ((4/3)+0i)

Overloads:

• #/(arg0) ⇒ BigDecimal

  Parameters:

  Returns:
• #/ ⇒ void

  This method returns an undefined value.

#to_d ⇒ BigDecimal

Returns the value of int as a BigDecimal.

require 'bigdecimal'
require 'bigdecimal/util'

42.to_d   # => 0.42e2
