The invention relates to a method for compressing and decompressing sequences of floating-point numbers. The compression method comprising steps of: determining a minimum value and a maximum value of the floating point numbers of said sequence, determining a quantization step value as a function of said minimum and maximum values, compressing each floating point number of said sequence by applying to the floating point number a linear quantization between said minimum and maximum values and using said quantization step value, and inserting each compressed value resulting from said compression step in a binary sequence.
L'invention concerne un procédé de compression et de décompression de séquences de nombres à virgule flottante. Le procédé de compression consiste: à déterminer une valeur minimum et une valeur maximum des nombres à virgule flottante de ladite séquence; à déterminer une valeur d'étage de quantification en fonction desdites valeurs minimum et maximum; à comprimer chaque nombre à virgule flottante de ladite séquence par l'application d'une quantification linéaire entre lesdites valeurs minimum et maximum, au moyen de ladite valeur d'étage de quantification; et à insérer chaque valeur comprimée résultant de ladite étape de compression dans une séquence binaire.
