The size of theBoolean data typein C programming is not specified in the C standard, and it can vary depending on the implementation of the compiler and the architecture of the computer. However, in most implementations, theBoolean data typeis represented using one byte, which means that aBoo...
Please can anyone help with suggestions about how to define a Boolean data type in C? For my logical tests now I use one integer and if the condition is TRUE the integer takes value 1 and if FALSE the integer gets 0. But that's rather complicated. If anyone has a simpler way pl...
A Boolean is a data type in Scala programming language (and another programming also), that is used or Boolean algebra. It has two valid values i.e. true and false.We declare it using the var keyword, with optional data type specified as Boolean. The default value for this data type ...
boolean: The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined. 上面的说的很清楚,boolean 值只有 tru...

In this example, it is necessary to use floating point values. The low precision of the float data type does not pose a problem in this case. distance = 0.1f; 100m is 0.1km. time = 9.87f / 3600; 9.87s is 9.87/60*60h.
