BigDecimal_div3(int argc, VALUE *argv, VALUE self)

    VALUE b,n;

    return BigDecimal_div2(self, b, n);
}

Divide by the specified value.

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 BigDecimal.mode.

If digits is 0, the result is the same as for the / operator or quo.

If digits is not specified, the result is an integer, by analogy with Float#div; see also BigDecimal#divmod.

See BigDecimal#/. See BigDecimal#quo.

Examples:

Example

a = BigDecimal("4")
b = BigDecimal("3")

a.div(b, 3)  # => 0.133e1

a.div(b, 0)  # => 0.1333333333333333333e1
a / b        # => 0.1333333333333333333e1
a.quo(b)     # => 0.1333333333333333333e1

a.div(b)     # => 1
