title: No kotlin.Math class in kotlin 1.2 as it is said in the documentation
body: <p>I have been dealing with kotlin multiplatform alot recently, and I totaly understand the nature of the development. Initially, I had my own expected Math class (in a common module) and I had actual classes in the JS and JVM environment. </p>
  
  <p>Since I like to read the documentations, I found that the Math liblary has been added to the standard liblary since kotlin 1.2. this trouble me as I am using kotlin 1.2.51 and I get an error trying to access the class from kotlin.Math in my common module and any of my platform specific module. </p>
  
  <p>What am I not geting? How do I get access to the kotlin.Math class in my common module?</p>
