int8 conversion to one byte integer representation int16 conversion to 2 bytes integer representation int32 conversion to 4 bytes integer representation uint8 conversion to one byte unsigned integer representation uint16 conversion to 2 bytes unsigned integer representation uint32 conversion to 4 bytes unsigned integer representation y = int8(X) y = int16(X) y = int32(X) y = uint8(X) y = uint16(X) y = uint32(X) X a matrix of floats or integers. y a matrix of integers coded on one, two or four bytes. These functions convert and store data to one, two or four bytes integers. These data types are especially useful to store big objects such as images, long signals,... y = int8(X) return numbers in the range [-128, 127] y = uint8(X) return numbers in the range [0, 255] y = int16(X) return numbers in the range [-32768, 32767] y = uint16(X) return numbers in the range [0, 65535] y = int32(X) return numbers in the range [-2147483648, 2147483647] y = uint32(X) return numbers in the range [0, 4294967295] If X has numbers with a fractional part, Scilab rounds them to the nearest integer toward zero. double inttype iconvert
