[−][src]Trait rug::ops::RemRoundingFrom
Compound assignment to the rhs operand and rounding variants of the remainder operation.
Examples
use rug::ops::RemRoundingFrom; struct I(i32); impl RemRoundingFrom<i32> for I { fn rem_trunc_from(&mut self, lhs: i32) { self.0 = lhs % self.0; } fn rem_ceil_from(&mut self, lhs: i32) { let r = lhs % self.0; let change = if self.0 > 0 { r > 0 } else { r < 0 }; self.0 = if change { r - self.0 } else { r }; } fn rem_floor_from(&mut self, lhs: i32) { let r = lhs % self.0; let change = if self.0 > 0 { r < 0 } else { r > 0 }; self.0 = if change { r + self.0 } else { r }; } fn rem_euc_from(&mut self, lhs: i32) { let r = lhs % self.0; self.0 = if r < 0 { if self.0 < 0 { r - self.0 } else { r + self.0 } } else { r }; } } let mut rem_ceil = I(3); rem_ceil.rem_ceil_from(10); assert_eq!(rem_ceil.0, -2);
Required methods
fn rem_trunc_from(&mut self, lhs: Lhs)
Finds the remainder when the quotient is rounded towards zero.
fn rem_ceil_from(&mut self, lhs: Lhs)
Finds the remainder when the quotient is rounded up.
fn rem_floor_from(&mut self, lhs: Lhs)
Finds the remainder when the quotient is rounded down.
fn rem_euc_from(&mut self, lhs: Lhs)
Finds the positive remainder from Euclidean division.
