Useful values for scaler are 1, 10 and 100. the easiest technique is to just assign float to int, for example: this will truncate everything behind floating point or you can round your float number before. For example, the float value 10.9 is also converted to the integer value 10. This type of static_cast is used to implement move semantics in std::move. */ By glancing at the line of code above, you will immediately determine the purpose of the cast as it is very explicit.

This allows the compiler to generate a division with an answer of type float. The equivalent method would be (and the way you should do it). The range for the transformed values runs from 0 to 1300. B = cast(A,newclass) returns the data in A converted to the data type (class) newclass, where newclass is the name of a built-in data type compatible with A.Any values in A that are outside the range of newclass are truncated in B to the nearest endpoint.. In C++, when you convert a float to an integral type, the value is always truncated. This feature will be useful. You may want to add some epsilon value first before converting.
