jpmesh 1.2.1 (2020-05-06)

• Meshcode evaluation is now more stringent.
  • Fixed a problem where a non-existent mesh code would return an incorrect value when given as input (#45).

jpmesh 1.2.0 (2020-03-26)

• API changes to functions that take mesh_size (#35). It has been changed to a numeric value in km unit instead of the mesh size string.

coords_to_mesh(141.3468, 43.06462, mesh_size = "10km")

to

coords_to_mesh(141.3468, 43.06462, mesh_size = 10)

• Add mesh_convert() that mesh size can be changed freely.

# Scale up
mesh_convert("52350432", 80)
# Scale down
