Description
Using mathjs@5.4.1
When the null value is on the right side, the correct error is thrown (actual: null):
> require('mathjs').eval('1 > null')
TypeError: Unexpected type of argument in function larger (expected: number or Array or DenseMatrix or SparseMatrix or string or boolean or Matrix or BigNumber or Complex or Fraction, actual: null, index: 1)
However, when the null value is on the left side, the error mistakenly identifies the right side as the source of the problem (actual: number):
> require('mathjs').eval('null > 1')
TypeError: Unexpected type of argument in function larger (expected: Array or DenseMatrix or SparseMatrix or Matrix, actual: number, index: 1)
