What does value 1 mean

value>>=1 is equivalent to value=value>>1

value=value>>1, which means that the value is shifted one place to the left and then assigned to the value itself, under the premise of not exceeding the defined range, the left shift is multiplied by 2 The operation speed is much faster than value=value*2 I hope to learn and progress Hehe Come on.

For example, if value = 234 is converted to binary, it is 11101010, then value>>=1 is the binary number is shifted one place to the right, becomes 01110101, and then assigned to value, which is converted to a decimal number is 117.

In the same way, this symbol indicates a shift to the left, but whether it is a left shift or a right shift, the empty space is a fill of 0, which should be noted.

The answers of the first two people are faulty, don't talk nonsense if you don't understand, it's really misleading to the public, I deliberately checked the information to figure it out.

In simple terms: e.g. a=1111 0000

then a=a>>2 to get a=0011 1100, that is, remove the two zeros on the far right of the original a, move 2 bits to the right as a whole, and leave two empty bits on the left, and make up 0.

then a=a<<2 gets a=1100 0000, that is, remove the two 1s on the far left of the original a, move 2 places to the left as a whole, and leave two empty bits on the far right, and make up 0.

This is very clear.

value is one of the commonly used form control properties, including command group controls, text boxes, boxes, checkboxes, option group controls, list boxes, and combo boxes.

If value 1 can be defined, it should be a property of the command group control, which means specifying the current state of the command group. The default type of this property is numeric.

As for the value equal to 1 or 0, it should be defined by itself.

When there is a calculation relationship between multiple text boxes, that is, when you want to perform the calculation, the value of the property value of the text box cannot be "none", you can set it to 0 or 1 to perform the operation. Hey.

If the value of dq is 1, do an "or" operation with the value of the 0x80, and then save the result in the value.

cells(c, 1).value = i

This means assigning an i to the cell in column 1 of row c

This function is to put the first column from 1 to 9, then each number corresponds to the second column from 2 to 10, and then each number in the second column corresponds to the third column from 3 to 11, and then remove 1 column + 3 columns = 2 times 2 columns.

Endi is short for Endif.

value=1 value=0 value=""There is no special meaning, it is to set the value of the value property, the front rot front track is set to 2 sets the posture as a numeric type, and the latter one is set as an empty string.

There are three kinds of values, 0 means that it is not executed, 1 means it is executed, and 3 means that it is forbidden for users to execute, and it is grayed out. These are specific to the value of the check, unlike the option.

There are three states for the value attribute of the checkbox: 0 - unchecked 1 - checked 2 - not selected. This property can be set in ** (you can set this property to at will), and it will also be set to the control by clicking on it (1 is checked, and 0 is unchecked when you click again, and the value property cannot be set to 2 by checking the control alone).

In addition, the state of the checkbox can also be used as a judgment condition for the if statement, and the events triggered by the selected and unchecked states can be programmatically implemented.

Indicates that the checkbox widget is clicked, and =0 indicates that it is not clicked.

When the checkbox control is selected, the control will show x, and when the checkbox control is cleared, the x disappears. This control can be used to provide true, false, or yes no options. You can use the checkbox control in a group to display multiple choices, allowing you to select one or more of them.

You can also programmatically set the value of the checkbox by the value property.

value is set to:

Checkbox control 0 is not checked (default), 1 is checked, and 2 is grayed out (dimmed).
