Examples

Imagine you measured a rectangular table whose sides measure 1.5m and 80cm with ruler with precision up to 1mm. Then, you can initialize the Value as

  • Python:
from uncvalue import Value
L1 = Value(1.5, 1e-3)
L2 = Value(0.8, 1e-3)
  • Julia:
using UncValue
L1 = Value(1.5, 1e-3)
L2 = Value(0.8, 1e-3)

You now want to calculate the area of the table, so you multiply both lengths

  • Python:
A = L1 * L2
print(A)
  • Julia:
A = L1 * L2
println(A)

and obtain as outcome (1200.0 ± 1.7)·10^-3.

Of course, it is possible to perform more complex operations like

  • Python (numpy required, functions from python math will only compute the value)
import numpy as np
print(L1 ** L2)  # power -> (13831.6 ± 9.3)·10^-4
print(np.sin(L1))  # sinus -> (99749.5 ± 7.1)·10^-5
print(np.exp(L2))  # exponential -> (2225.5 ± 2.2)·10^-3
  • Julia
println(L1^L2)  # power -> (13831.6 ± 9.3)·10^-4
println(sin(L1))  # sinus -> (99749.5 ± 7.1)·10^-5
println(exp(L2))  # exponential -> (2225.5 ± 2.2)·10^-3
