instance method

Numeric#floor

num.floor([ndigits]) → integer or float

static VALUE
num_floor(int argc, VALUE *argv, VALUE num)
{
    return flo_floor(argc, argv, rb_Float(num));
}

Returns the largest number less than or equal to num with a precision of ndigits decimal digits (default: 0).

Numeric implements this by converting its value to a Float and invoking Float#floor.
