# Euclidean
- [Euclidean Division and Euclidean Modulo](https://en.wikipedia.org/wiki/Euclidean_division) for [Nim.](https://nim-lang.org)
# Use
```nim
import euclidean
echo euclideanDivision(-3, 5) # -3 / 5
echo euclideanModulo(-3, 5) # -3 mod 5
```
- You can use `import euclideanDivision as eDiv` or similar for short name, etc.
- You can use `import euclideanModulo as eMod` or similar for short name, etc.
- Remember results will be different than standard library `system` Divison and Modulo.
- Remember results will be different than standard library `math` Divison and Modulo.
- No dependencies. Uses `limits.h`.
- See http://wikipedia.org/wiki/Modulo_operation http://wikipedia.org/wiki/Euclidean_division
# FAQ
- This already exists in the Standard Library on `math.floorDiv`, `math.floorMod` ?
- This already exists in the Standard Library on `system./`, `system.mod` ?
**Nim**
```nim
from math import floorDiv, floorMod
echo "system.`/` Versus euclidean.euclideanDivision:"
echo "\tEuclideans Division\t-3 / 5 =\t", euclideanDivision(-3.cint, 5.cint)
echo "\tNim StdLib Division\t-3 / 5 = \t", -3.cint / 5.cint, "\n"
echo "system.`mod` Versus euclidean.euclideanModulo:"
echo "\tEuclideans Modulo\t-3 mod 5 =\t", euclideanModulo(-3.cint, 5.cint)
echo "\tNim StdLib Modulo\t-3 mod 5 =\t", -3.cint mod 5.cint, "\n\n"
echo "math.floorDiv Versus euclidean.euclideanDivision:"
echo "\tEuclideans Division\t5 / -3 =\t", euclideanDivision(5.cint, -3.cint)
echo "\tNim Floor Division\t5 / -3 = \t", floorDiv(5, -3), "\n"
echo "math.floorMod Versus euclidean.euclideanModulo:"
echo "\tEuclideans Modulo\t5 mod -3 =\t", euclideanModulo(5.cint, -3.cint)
echo "\tNim Floor Modulo\t5 mod -3 = \t", floorMod(5, -3)
```
**Results**
```
system.`/` Versus euclidean.euclideanDivision:
Euclideans Division -3 / 5 = -1
Nim StdLib Division -3 / 5 = -0.6
system.`mod` Versus euclidean.euclideanModulo:
Euclideans Modulo -3 mod 5 = 2
Nim StdLib Modulo -3 mod 5 = -3
math.floorDiv Versus euclidean.euclideanDivision:
Euclideans Division 5 / -3 = -1
Nim Floor Division 5 / -3 = -2
math.floorMod Versus euclidean.euclideanModulo:
Euclideans Modulo 5 mod -3 = 2
Nim Floor Modulo 5 mod -3 = -1
