use u64 inside investor data account

[AlphaGergedan]

We use f32 for the values stored in the investor data account:

#[derive(AnchorSerialize, AnchorDeserialize, Clone)]
pub struct Investor {
    pub identifier: Pubkey,             // Investor address
    pub amount: f32,                    // Total amount invested
    pub net_profit: f32,                // Total net profit, cannot be negative
}

Shouldn't we use u64 for these to represent the num. of lamports in solana? @DogukanGun

We should store as u64. Decimals will represent the real value but as I remember we represent the amount of a token without decimal.

So 1e9 lamports equals 1 SOL?. One lamport is the smallest unit in solana right, so we can store lamports (the smallest unit in solana)?.

Yes but we are gonna work with spl tokens so u32 or u64 are better. If we worked with native token than then lamport is logical. @AlphaGergedan
