Static random
Static sub
- sub(lhs, rhs, overflow?): Int
Add
lhstorhsand return the resulting value.Parameters
- lhs: Int
- rhs: Int
Optionaloverflow: OverflowBehavior
Returns Int
Binary integer with the underlying value represented by a BN.js instance. Follows C++11 standard for arithmetic operators and conversions.
Note
This type is optimized for correctness not speed, if you plan to manipulate integers in a tight loop you're advised to use the underlying BN.js value or convert to a JavaScript number first.
