Description: First, introduce the tuple conversion "1 byte =8 bits". The default length of a value of type int is 4 bytes, or 32 bits. The maximum length of binary conversion is 2 31(0-31), which can be divided into positive and negative values. The result of calculation is the range of values of type int.
What is the value range of int data in C++? Int in standard C++ has different bytes according to different systems. On most platforms, int has 4 bytes, so the range it can represent is 2 to the 32nd power. What is said upstairs is not quite right. It should mean int 4
-216 ~ 216-1(represented by a square)
According to different needs, int includes the following definitions:
Unsigned short integer unsigned double-byte short integer
Short Integer Signed Double Byte Short Integer -32768 ~ 32767
Unsigned int unsigned 4-byte integer 0 ~ 2 32- 1
Int 4 byte shaping
Int 64 64-bit (8 bytes) shaping -2 32 ~ 2 32- 1
What is the pH range? 0- 14. Hope to adopt.
What is the range of rand ()? Rand () is a random number rand()% 100, but the remainder is 100.
number = rand()% 100； So this number is a number from 0 to 99.
(For example, the remainder is because10/%100 =1100%100 = 0 99%100 = 99).
Then the number++; So the range becomes a number from 1 to 100.
What is the range of -sinx [- 1, 1]? Because sinx is greater than or equal to-1 and less than or equal to 1, the direction change of inequality after adding a negative sign to sinx can also be seen by drawing the image of function y=-sinx, and the value range is [- 1, 6544.
What is the range of x in LGX, LOGX, LNX? The range of values is greater than 0, that is, 0 to positive infinity.
What is the range of TTL? 0-255
The voltage range of TTL power supply is 4.5v-5.5v. The maximum input value of TTL value range is VCC+0.5V, and the input value range is
0-VCC+0.5V Because the input high and low voltages specified by various TTL circuits are different, the output is 0-VCC, and some circuits are OC gates, so the output can be high voltage.
What is the range of 1.5? five
In arctanα, what is the range of α? What is the value range of tanα as a whole at this time? The overall value range from-90 to 90 is negative infinity to positive infinity.
