我正在为sin个三角函数实现CORDIC算法.为了做到这一点，我需要硬编码/计算一组反正切值.现在，我的函数seems将以打印的精度工作(经Wolfram Alpha验证)，但我希望能够打印我的f32的所有32位精度.我该怎么做？
fn generate_table() {
let pi: f32 = 3.1415926536897932384626;
let k1: f32 = 0.6072529350088812561694; // 1/k
let num_bits: uint = 32;
let num_elms: uint = num_bits;
let mul: uint = 1 << (num_bits - 2);
println!("Cordic sin in rust");
println!("num bits {}", num_bits);
println!("pi is {}", pi);
println!("k1 is {}", k1);
let shift: f32 = 2.0;
for ii in range(0, num_bits) {
let ipow: f32 = 1.0 / shift.powi(ii as i32);
let cur: f32 = ipow.atan();
println!("table values {}", cur);
}
}
