Methods
_getBPValue
▸ _getBPValue(_binStep): u256
Returns the (1 + bp) value as a 128.128-decimal fixed-point number
Parameters
| Name | Type | Description |
|---|---|---|
_binStep | u64 | The bp value in [1; 100] (referring to 0.01% to 1%) |
Returns
u256
The (1+bp) value as a 128.128-decimal fixed-point number
Defined in
assembly/libraries/BinHelper.ts:37

Defined in
assembly/libraries/BinHelper.ts:25
power
▸ power(x, y): u256
Returns the value of x^y. It calculates 1 / x^abs(y) if x is bigger than 2^128.
At the end of the operations, we invert the result if needed.

x | u256 | The unsigned 128.128-binary fixed-point number for which to calculate the power |
y | i64 | A relative number without any decimals, needs to be between ]-2^20; 2^20[ |
Returns
u256
The result of x^y
