I want to store decimal value in a storage variable and later use that variable at same precision in the formula later internally

Question

I want to store uint public MINTING_VELOCITY = 0.000002;

And later use it in the formula: A x t x MINTING_VELOCITY ,where A = 2000 ,t(staking_duration_time) = 120

Issue is currently MINTING_VELOCITY is reading 0.

How to take the exact/fetch the decimal value with exact precision?Please follow the code shared in the screenshot to understand the scenario better

How to achieve that via solidity .Please help!

Does this help you? What fixed or float point math libraries are available in solidity? — Paul Razvan Berg, Feb 08 '21 at 09:53

Just use cast to integer arithmetic:

MINTING_VELOCITY = 2
ACCURACY_RATIO = 1000000

And the formula converts to: A x t x MINTING_VELOCITY / ACCURACY_RATIO
