Constant MIN_10_EXP 

pub const MIN_10_EXP: i32 = f32::MIN_10_EXP; // -37i32

👎Deprecating in a future version: replaced by the MIN_10_EXP associated constant on f32

Minimum possible normal power of 10 exponent. Use f32::MIN_10_EXP instead.

Examples

// deprecated way
let min = std::f32::MIN_10_EXP;

// intended way
let min = f32::MIN_10_EXP;
