Pascal Language Structure
ConstantsInteger and Real Number Constants
Integer constants are values that can be represented in either decimal
(base 10) or hexadecimal (base 16). A decimal number is a string of digits
(0-9) that may be preceded with a plus or minus sign. A hexadecimal
number is preceded by a dollar sign ($) followed by a string of digits and
the characters A through F. The following are valid integer numbers:
100 -255 100500 $FE $ABCD
Real constants are numbers that contain an integer portion, a fractional
portion, and an exponent. Use real constants when the fraction of a number
is necessary. The syntax for real constants is as follows:
[+|-] digits [.digits] [E [+|-] digits]
The letter E represents the exponent part of the real number.
Exponents are powers of ten. Both integer and real constants may not contain
space characters. The following are valid real constants:
1.0 -205.13 9019.31E100 40.71E-10
The current version of TMT Pascal
compiler does not provide constants of Extended type.
