Convert operand to number

 Action    name: OpNumber
 

This command converts immediate operand(s) type of the current instruction/data to a number. That way, you can delete suspicious mark of the item.

The number is represented in the default radix for the current processor (usually hex, but octal for PDP-11, for example).

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Convert operand to hexadecimal number

 Action    name: OpHex
 

This command converts immediate operand(s) type of the current instruction/data to hex number. So you can delete suspicious mark of the item.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Convert operand to decimal number

 Action    name: OpDecimal
 

This command converts the immediate operand(s) type of the current instruction/data to decimal. Therefore, it becomes a 'number'.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Convert operand to octal number

 Action    name: OpOctal
 

This command makes the current instruction or data operand type octal. IDA always uses 123o notation for octal numbers even if the current assembler does not support octal numbers.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Convert operand to binary number

 Action    name: OpBinary
 

This command makes the current instruction or data operand type binary. IDA always uses 123b notation for binary numbers even if the current assembler does not support binary numbers.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Convert operand to floating point number

 Action    name: OpFloat
 

This command makes the current operand type floating point.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise, all other operands will be affected.

Toggle leading zeroes

 Action    name: ToggleLeadingZeroes
 

This command displays or hides the leading zeroes of the current operand. Example: if the instruction looked like this:

        and     ecx, 40h

then after applying the command it will look like this:

        and     ecx, 00000040h

If you prefer to see leading zeroes in all cases, then open the calculator and enter the following expression: set_inf_attr(INF_GENFLAGS, get_inf_attr(INF_GENFLAGS) | INFFL_LZERO); This will toggle the default for the current database and all numbers without leading zeroes will become numbers with leading zeroes, and vice versa.
