Reverse a base 100 number

[V Coder]

Hi, what's the quickest way to reverse a 100 number? Max value 99.

(x%10)*10 + (x\10)

Can we do this in parallel (SIMD)? Is there a better equation? Thanks.

Try AAM, AAD and xchg (with value in AL and result in AL):

Code Select Expand


AAM
XCHG AL, AH
AAD

What do you mean by base 100, and reverse. Can you give an example.

I ask because a base 100 number with a max value of 99 is actually a single digit number.
