Float#*

(::BigDecimal) -> ::BigDecimal

(::Complex) -> ::Complex

(::Numeric) -> ::Float

self * other → numeric

VALUE
rb_float_mul(VALUE x, VALUE y)
{
    if (FIXNUM_P(y)) {
        return DBL2NUM(RFLOAT_VALUE(x) * (double)FIX2LONG(y));
    }
    else if (RB_BIGNUM_TYPE_P(y)) {
        return DBL2NUM(RFLOAT_VALUE(x) * rb_big2dbl(y));
    }
    else if (RB_FLOAT_TYPE_P(y)) {
        return DBL2NUM(RFLOAT_VALUE(x) * RFLOAT_VALUE(y));
    }
    else {
        return rb_num_coerce_bin(x, y, '*');
    }
}

Returns a new Float which is the product of self and other:

Example

f = 3.14
f * 2              # => 6.28
f * 2.0            # => 6.28
f * Rational(1, 2) # => 1.57
f * Complex(2, 0)  # => (6.28+0.0i)
