Basic data compression to save watch memory use.

Good morning everyone, 

In one of my applications I have a very large array that is full of float values,  ( up to around 150 float values ), and I would like to convert each array float into a 4 digit  value ( always with two decimal places, and allways with value less that 99, and always an integer ), and then combine several of the array values into a single number. 

For example [1.2344667,24.565544,32.342354,77.3424234]   would become 0123245732347734

My array of 150 float values, would then become an array of 33 numbers..... and I could have lots of these arrays.

I need to retain accuracy with the number, so my question is how many of these 4 digit, non signed , non decimal  numbers should I be able to group and store as non signed integers?

I might have for example, 200 arrays each with 150 values, and the watch memory cannot cope with that number of vlaues.
