Template documentationUsage
- Normal evaluation
-
‟{{eval|3 / 4}}”gives ‟0.75”.‟{{eval|3 * 4}}”gives ‟12”.‟{{eval|3 + 4}}”gives ‟7”.‟{{eval|3 - 4}}”gives ‟-1”.‟{{eval|3 mod 4}}”gives ‟3”.
- Error handling
-
‟{{eval|3 / 0}}”gives ‟[expression “3 / 0” is wrong]”, because division by 0 is undefined.‟{{eval|1 + {{eval|3 / 0}}}}”gives ‟[expression “1 + [expression “3 / 0” is wrong]” is wrong]”, this is a case of nested error messages.
