Trait ndarray_rand::rand_distr::num_traits::WrappingNeg [−][src]
Performs a negation that does not panic.
Required methods
pub fn wrapping_neg(&self) -> Self[src]
Wrapping (modular) negation. Computes -self,
wrapping around at the boundary of the type.
Since unsigned types do not have negative equivalents
all applications of this function will wrap (except for -0).
For values smaller than the corresponding signed type’s maximum
the result is the same as casting the corresponding signed value.
Any larger values are equivalent to MAX + 1 - (val - MAX - 1) where
MAX is the corresponding signed type’s maximum.
use num_traits::WrappingNeg; assert_eq!(100i8.wrapping_neg(), -100); assert_eq!((-100i8).wrapping_neg(), 100); assert_eq!((-128i8).wrapping_neg(), -128); // wrapped!
