Limits for Data Types

Numeric data types have minimum values and maximum values based on their byte size.

Table 50. Limits for Data Types
Data Type Minimum Maximum
int8 -128 127
int16 -32.768 32.767
int32 -2.147.483.648 2.147.483.647
uint8 0 255
uint16 0 65.536
uint32 0 4.294.967.295
real32 -3.402823466385e+38 3.402823466385e+38
real64 -1.797693134862e+308 1.797693134862e+308

Query the minimum and maximum limits of a data type using :min or :max. The data type of the target variable must be within the limits of the requested data type.

  • The following calls are valid because the attribute return values or calculations are within the limits of the corresponding variable data types.
    • int8 maxInt8 = int8:max
    • int8 minInt8 = int8:min
    • uint32 maxUInt32 = uint16:max
    • int8 var1 = int32:max + int32:min
    • int8 var2 = int8:min + 5
  • The following calls are not valid because the attribute return values or calculations are outside the limits of the corresponding variable data types.
    • uint16 minInt32 = int32:min
    • int8 maxUInt16 = uint16:max
    • int8 var1 = int16:min / 2
    • int8 var2 = int8:min - 255

The rules apply analogously to the attributes of floating-point numbers.
