How to define the max number for an uint

[fmulder]

I got a weird question from a colleague and I was unable to answer.

The following script code will correctly output the numerical value 2147483648

Code: Select all

  uint uMask = 1

When no type suffix is used the control interpreter uses the data type integer.
So to define a constant outside the integer range you need to use a suffix, these suffixes can be found in the online help -> CONTROL -> Introduction to CONTROL -> Data types

• uint/unsigned: u or U
• long: l or L
• ulong: ul or UL

By the way for defining the max/min number you can use one of the max/min functions, like 'maxUINT()' (which returns 4294967295)

Just to clarify. This is the correct way to define the largest possible unsigned integer:

Code: Select all

  uint uMasker = 2147483648u;
  DebugN( uMasker );

[Gertjan van Schijndel]

Yes, that is the correct way to define an unsigned with the value 2147483648.

The correct way to define the largest possible unsigned integer:

Code: Select all

uint uMasker = maxUINT();   // or
uint uMasker = 0xFFFFFFFFu; // or
uint uMasker = 4294967295u;

Yes, you are right.
I guess it is time to go home. This was a stupid mistake

Thanks
