by default any float value is double
double or float
Of course, you should have tested: float x= -1.0;
PCM is preferable because of better SNR characteristics.
Decimal numbers are real numbers. In C and C++ we use the float, double and long double data types to represent real numbers.
The number of bytes occupied by a specific data type depends on the implementation. In general, the double data type is eight bytes long, but you can check it using sizeof(double). In 16-bit,32-bit compilers double size is 8 bytes.It looks like float because it stores scientific and financial like big float values.
data types supported by "C" are int , float , char , long , double , uint
byte, short, int, long, char, float, double, boolean
byte short long int char float double boolean
Percentage is not a data type. A percentage of something would need a floating point data type to store it. One of the following data types. float double long double (in gcc, not sure about other compiler systems)
"float" should be sufficient
If two numbers are involved in a calculation (in this case a multiplication), the result is converted to the more precise data type, to avoid data loss. Even though between long and double data can be lost in either direction, a number with decimals (such as double) is generally considered to be more precise than a number without decimals (such as long). Even though languages such as Java also have a "float" data type, "double" is normally used by default in cases such as these, because of the greater precision. However, you can convert explicitly to float, if you like, using a cast. (Float uses 4 bytes, while double uses 8 bytes.)
eight primitive data types are: -boolean -char -byte -short -int -long -double -float
