10.1.6 Number Constants

Number values can appear as binary numbers, octal numbers, decimal numbers and

hexadecimal numbers. If an integer value is not a decimal number, you must write its

base followed by the number sign (#) in front of the integer constant. The values for

the numbers 10-15 in hexadecimal numbers will be represented as always by the

letters A-F.

You may include the underscore character within the number.

Examples:

14 (decimal number)

2#1001_0011 (dual number)

8#67 (octal number)

16#A (hexadecimal number)

These number values can be from the variable types BYTE, WORD, DWORD, SINT,

USINT, INT, UINT, DINT, UDINT, REAL or LREAL.

Implicit conversions from "larger" to "smaller" variable types are not permitted. This

means that a DINT variable cannot simply be used as an INT variable. You must use

the type conversion.

10.1.7 REAL/LREAL Constants

REAL and LREAL constants can be given as decimal fractions and represented

exponentially. Use the standard American format with the decimal point to do this.

Example:

7.4 instead of 7,4

1.64e+009 instead of 1,64e+009

1 2 ... 503 504 505 506 507 508 509 510 511 512 513 ... 843 844
