[+] Show declaration

pub struct BpfSqrtI {}

[−] Expand description

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};

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