No method named "pow" found for type "u256"

Trying to do this: new_fee: val.as_u256() * 10.as_u256() ** expo.as_u256() but getting an error: No method named "pow" found for type "u256", is pow not supported for u256? or am I using the wrong syntax?

I’ve also tried variants like:

  • val.as_u256() * 10.as_u256().pow(expo.as_u256())
  • val.as_u256() * u256::from(10).pow(expo.as_u256())
    and they all don’t work

Since u256 is special in the sense that they cannot fit into the primative 64 bit registers they are treated slightly differently.

However using the power function, logarithm, square roots they all depend on the math library inside the standard library like so:

thanks for the context! managed to get it working by importing
use std::math::*;
