Resolution for problem with reading of XIOS when compilation done in debug mode, solution by Y. Meurdesoif. See ticket #472
In XIOS, the division is done on the full tabel, even if there is a test to protect from zero divison. Therefor, the nomintator needs +1e-100 to avoid zero divison. This is already done on other fields in context_input_orchidee.xml.
