instance method

Numeric#to_int

() -> ::Integer

to_int → integer

static VALUE
num_to_int(VALUE num)
{
    return num_funcall0(num, id_to_i);
}

Returns self as an integer; converts using method to_i in the subclass of Numeric. (Numeric itself does not define to_i.)

Of the Core and Standard Library classes, only Rational and Complex use this implementation.

Examples:

Example

Rational(1, 2).to_int # => 0
Rational(2, 1).to_int # => 2
Complex(2, 0).to_int  # => 2
Complex(2, 1).to_int  # Raises RangeError (non-zero imaginary part)
