instance method

Float#<

(::Numeric) -> bool

self < other → true or false

static VALUE
flo_lt(VALUE x, VALUE y)
{
    double a, b;

    a = RFLOAT_VALUE(x);
    if (RB_INTEGER_TYPE_P(y)) {
        VALUE rel = rb_integer_float_cmp(y, x);
        if (FIXNUM_P(rel))
            return RBOOL(-FIX2LONG(rel) < 0);
        return Qfalse;
    }
    else if (RB_FLOAT_TYPE_P(y)) {
        b = RFLOAT_VALUE(y);
    }
    else {
        return rb_num_coerce_relop(x, y, '<');
    }
    return RBOOL(a < b);
}

Returns whether the value of self is less than the value of other; other must be numeric, but may not be Complex:

Example

2.0 < 3              # => true
2.0 < 3.0            # => true
2.0 < Rational(3, 1) # => true
2.0 < 2.0            # => false

Float::NAN < Float::NAN returns an implementation-dependent value.
