use Core.read

def main():
    str text = read_str();
    print($"entered text: \"{text}\"\n");

read_i32

The read_i32 function has no parameters and returns a i32 value. It is used to read i32 values from the console. It can throw an error if the entered text is not parsable to an signed integer value.

use Core.print
use Core.read

def main():
    i32 num = read_i32();
    print($"entered i32: {num}\n");

read_i64

The read_i64 function has no parameters and returns a i64 value. It is used to read i64 values from the console. It can throw an error if the entered text is not parsable to an signed integer value.

use Core.print
use Core.read

def main():
    i64 num = read_i64();
    print($"entered i64: {num}\n");

read_u32

The read_u32 function has no parameters and returns a u32 value. It is used to read u32 values from the console. It can throw an error if the entered text is not parsable to an unsigned integer value.

use Core.print
use Core.read

def main():
    u32 num = read_u32();
    print($"entered u32: {num}\n");

read_u64

The read_u64 function has no parameters and returns a u64 value. It is used to read u64 values from the console. It can throw an error if the entered text is not parsable to an unsigned integer value.

use Core.print
use Core.read

def main():
    u64 num = read_u64();
    print($"entered u64: {num}\n");

read_f32

The read_f32 function has no parameters and returns a f32 value. It is used to read f32 values from the console. It can throw an error if the entered text is not parsable to an floating point value.

use Core.print
use Core.read

def main():
    f32 num = read_f32();
    print($"entered f32: {num}\n");

read_f64

The read_f64 function has no parameters and returns a f64 value. It is used to read f64 values from the console. It can throw an error if the entered text is not parsable to an floating point value.

use Core.print
use Core.read

def main():
    f64 num = read_f64();
    print($"entered f64: {num}\n");
