PRO variable_types ; This procedure demonstrates how to decalre variable types ; Set the variable x to a 16-bit signed integer with the value 25 x = 25 help, x x = fix(25) help, x x = 25S help, x ; Set the variable y to a 32-bit signed integer with the value 33000 y = 33000 help, y y = long(33000) help, y y = 33000L help, y ; Set the variable z to a 32-bit floating point with the value 4.0 z = 4. help, z z = float(4) help, z z = 4.0E+0 help,z ; Set the variable w to a 64-bit floating point with the value 2.338485968 w = 2.3384857 help, w w = 2.3384857D help, w w = double(2.3384857) help, w ; what was wrong with the first way we declared w???
