abs() Instance Public methods Returns the absolute value. BigDecimal('5').abs -> 5 BigDecimal('-3').abs -> 3

add(value, digits) Instance Public methods + Add the specified value. e.g. c = a.add(b,n) c = a + b digits If specified and less than the number of significant digits of the result, the result is rounded to that number of digits, according to ::mode.

as_json(*) Instance Public methods Marshal the object to JSON. method used for JSON marshalling support.

ceil(n) Instance Public methods Return the smallest integer greater than or equal to the value, as a BigDecimal. BigDecimal('3.14159').ceil #=> 4 BigDecimal('-9.1').ceil #=> -9 If n is specified and positive, the fractional part of the result has no more than that many digits. If n is specified and negative, at least that many digits to the left of the decimal point will be 0 in the result. BigDecimal('3.14159').ceil(3) #=> 3.142 BigDecimal('13345.234').ceil(-2) #=> 1

coerce(p1) Instance Public methods The coerce method provides support for Ruby type coercion. It is not enabled by default. This means that binary operations like + * / or - can often be performed on a BigDecimal and an object of another type, if the other object can be coerced into a BigDecimal value. e.g. a = ::new(â1.0â) b = a / 2.0 -> 0.5 Note that coercing a String to a BigDecimal is not supported by default; it requires a special compile-time option when building Ruby.

div(p1, p2 = v2) Instance Public methods See #quo

divmod(p1) Instance Public methods Divides by the specified value, and returns the quotient and modulus as BigDecimal numbers. The quotient is rounded towards negative infinity. For example: require 'bigdecimal' a = ::new(â42â) b = ::new(â9â) q,m = a.divmod(b) c = q * b + m a == c -> true The quotient q is (a/b).floor, and the modulus is the amount that must be added to q * b to get a.

eql?(p1) Instance Public methods Tests for value equality; returns true if the values are equal. The == and === operators and the eql? method have the same implementation for BigDecimal. Values may be coerced to perform the comparison: ::new('1.0') == 1.0 -> true

exponent() Instance Public methods Returns the exponent of the BigDecimal number, as an Integer. If the number can be represented as 0.xxxxxx*10**n where xxxxxx is a string of digits with no leading zeros, then n is the exponent.

finite?() Instance Public methods Returns True if the value is finite (not NaN or infinite)
