WebMATLAB stores numeric data as double-precision floating point (double) by default. To store data as an integer, you need to convert from double to the desired integer type. Use one of the conversion functions shown in the table above. For example, to store 325 as a 16-bit signed integer assigned to variable x, type WebX = 3.1416. X = double ( '3.1416') X = 1×6 51 46 49 52 49 54. This list summarizes the best practices for converting text to numeric values. To convert text to numeric values, use the str2double function. It treats string arrays, character vectors, and cell arrays of character vectors consistently.
