Tutorial How to get and use float in armv7-il2cpp

Numark

Awesome Active Platinian
Step 1: Go to this site

Step 2: Once opening, find "Decimal Floating-Point".

Step 3: Beside that, type in the number you want through 1-2000.

Step 4: Click "Rounded" or "Not Rounded", it doesn't matter which is which. Just choose one.

Step 5: Find "Single precision (32 bits):", DO NOT USE THE 64 BIT!!

Step 6: Above "Single precision (32 bits):", you should find "Hexadecimal".

Step 7: you should now find the Hexadecimal, if the numbers or letters is not there, then you haven't done STEP 3 yet.

Step 8. You should see a 4 Byte Hexadecimal, copy the 4 Byte.

Example: I chose the number 100 and clicked "Not Rounded", I scrolled down and found "Hexadecimal" above "Single precision (32 bits):"
You should see the Hexadecimal that has letters or numbers. The number I chose 100 and the Hexadecimal for that is 42C8. After that, copy that Hexadecimal.

Step 9: After copying the Hexadecimal... Go to armconverter.com.

Step 10: Make sure the page is Arm To Hex.

Step 11: Choose the architecture of Armv7.

Step 12: Now go into the text box and type in "Movt r0, #0x42C8" and you should find the hex value for it.

Float 100 Value = C8 02 44 E3

Congratulations, you now have the hex value of float 100.

Make sure to BX LR after the value of float, or just in case to end function.

BX LR = 1E FF 2F E1

Both = C8 02 44 E3 1E FF 2F E1

Thank you for understanding and learning.

I hope that this tutorial will help you guys. :)

.i use 2000 but still conversation failed
Click to expand...
2000 would be this in ARM:

"\xfa\x04\x04\xe3\x1e\xff\x2f\xe1"

Which is

FA 04 04 E3 1E FF 2F E1

The Number for 2000 in hex is:
44FA

So the Instruction would be:

MOV R0, #0x44FA
BX LR
