                it's using PowInt() only when pow.exponent is in range (-man*TTMATH_BITS_PER_UINT; 0]
                previously the powering 'hung' on an input like this: "(1+ 1e-10000) ^ 10e100000000"
                (there was 10e100000000 iterations in PowInt())
+    * fixed:   in function DegToRad(const ValueType & x, ErrorCode * err = 0) it is better
+               to make division first and then mutliplication -- the result is more
+               accurate especially when x is: 90,180,270 or 360
     * changed: UInt::FromString, added a parametr 'after_source'
                which is pointing at the end of the parsing string
     * changed: renamed: Big::PowUInt(UInt<pow_size> pow) -> Big::Pow(UInt<pow_size> pow)
