Sure.
Depending on what kind of code you're making, it may require a couple different things.
What it sounds like is you've found a code where you'd have a VISUAL value and need an ACTUAL value. So if you're searching for, say a visual value of 100 (00000064), you're going to have two actual codes to worry about. If you're search only turns up 1 result for your value, but doesn't lock it in, you may need to search for the FLOAT version of the value. In my example, it would be 42C80000. Values like that are common for like health bars and various gauges in a lot of games, but sometimes numerical values use them, too.
Vita games use both 32- and 64-bit float values, which can really ruin your day when searching for codes, since VitaCheat doesn't allow you to search for 64-bit float values.
--However--
You CAN search for at least the first eight digits of a 64-bit float value, and it'll usually work out pretty well. A LOOOOOOT of indie games use 64-bit float values. Like... A LOT.
Here's a link to the floating point converter I use. It's pretty easy to use:
Also, don't be afraid to crank up your search range. Some games go past the 91000000 address range, so that may help you find more results.
