iconvert

Arguments

X

a matrix of decimal numbers or encoded integers. Complex numbers not supported.

itype

an integer, a type of conversion.

y

a matrix of integers coded on 1, 2, 4 or 8 bytes.

Description

The iconvert function converts and stores data to 1, 2, 4 or 8 bytes integers.

itype = 0

return floating point numbers

itype = 1

return int8 numbers in the range [-128, 127]

itype = 11

return uint8 numbers in the range [0, 255]

itype = 2

return int16 numbers in the range [-32768, 32767]

itype = 12

return uint16 numbers in the range [0, 65535]

itype = 4

return int32 numbers in the range [-2147483648, 2147483647]

itype = 14

return uint32 numbers in the range [0, 4294967295]

itype = 8
