Struct solana_rbpf::syscalls::BpfSqrtI

pub struct BpfSqrtI {}

Compute and return the square root of argument 1, cast as a float. Arguments 2 to 5 are unused.

Examples

use solana_rbpf::syscalls::{BpfSqrtI, Result};
use solana_rbpf::memory_region::{MemoryRegion, MemoryMapping};
use solana_rbpf::vm::{Config, SyscallObject};
use solana_rbpf::user_error::UserError;

let mut result: Result = Ok(0);
let config = Config::default();
let memory_mapping = MemoryMapping::new::<UserError>(vec![MemoryRegion::default()], &config).unwrap();
BpfSqrtI::call(&mut BpfSqrtI {}, 9, 0, 0, 0, 0, &memory_mapping, &mut result);
assert_eq!(result.unwrap(), 3);
