What is range data type?
Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 – 2^8-1 i.e. 0-255 inside it.
How is float range calculated?
The decimal equivalent of a floating point number can be calculated using the following formula: Number = ( − 1 ) s 2 e − 127 1 ⋅ f , where s = 0 for positive numbers, 1 for negative numbers, e = exponent ( between 0 and 255 ) , and f = mantissa .
What is the range of double data type for a 16 bit compiler?
The keyword signed uses one bit for a sign and 15 bits for the magnitude of the number in a 16-bit machine. The keyword unsigned uses to store all the bits for the magnitude of the number and always positive….
| Type | Size(bits) | Range |
|---|---|---|
| double | 64 | 1.7E-308 TO 1.7E+308 |
| long double | 80 | 3.4E-4932 TO 1.1E+4932 |
