Get to Know the TSBroadcaster User Interface, Continued 

The TSBroadcaster supports input of a variety of data types through the UI. 

Wherever possible, data types that consist of a constrained list of values are entered 

using selection fields to minimize the risk of error.  
You may enter data, however, using a number of different formats as shown in the 

following table. 

 

Enter names using upper-, lower-, or mixed-case alphanumeric 

characters, including non-western alphanumerics, and the 

underscore character (“_”) 
Name fields are composed of an alphabetic character followed 

by zero or more alphanumeric characters or underscores. The 

software uses Java functions to check characters for validity to 

allow for non-ASCII characters, but it is recommended that 

names are restricted to the characters A-Z, a-z, 0-9 and “_” (the 

permitted characters from the ASCII character set). 

Enter integer numbers as either decimal numbers or unsigned 

hexadecimal numbers with a leading zero (“0x”) or (“0X”). 

Enter floating point numbers as signed or unsigned decimal 

numbers, with or without an embedded decimal point, and 

with or without a signed exponent designated by “E” or “e.”  
The term floating point means that there is no fixed number of 

digits before and after the decimal point; that is, the decimal 

point can float. A floating point number is a real number that 

can contain a fractional part. The following are floating-point 

numbers:  
• 

3.0  

• 

-111.5  

• 

½  

• 

3E-5  

The last example is a 

 shorthand for 

. It means 3*10-5 (or 10 to the negative 5th power 

multiplied by 3).
