Used markings:



<n>

numeric value

[ ]

<t>

text value

Note that the decimal separator for the floating point and the scientific numbers is not dependent on Windows' Regional Options. The separator is always a point (".") regardless of the regional settings.

 

Note that to use a double quotation mark as a part of a text constant, you need to precede the double quotation mark with a backslash. For example, a text constant defined as "ab\"c" will have the value ab"c.

 

Scientific notation was designed for easy representation of floating point numbers that are either very large or very small. A scientific number consists of base and exponent which are separated from each other with a letter E: <base>E<exponent>. The exponent is the exponent of 10. To calculate the real value of a scientific number, use the following formula: <base>*10<exponent>.
