- RXNUM.DLL adds type conversion and math operations to REXX.
-
- RXNUM handles positive integers in the range 0 ... 'FFFFFFFF'x
- Copy RXNUM.DLL into a directory of your LIBPATH.
-
- Functions:
-
- NUMINIT Initialisation
- Example: call RxFuncAdd 'numinit', 'RXNUM', 'numinit'
- call numinit()
-
- NUMDROP Drops the functions
- Example: call numdrop
-
- NUM2DEC Converts integer numbers to decimal form
- NUM2HEX " " " " hexadec form
- NUM2OCT " " " " octal form
- NUM2BIN " " " " binary form
- Syntax: RC = NUM2HEX('<d|h|o|b>||number')
- d - from decimal to hexadec
- h - from hexadec to hexadec
- o - from octal to hexadec
- b - from binary to hexadec
- Returns: <result string> <operand error> <result error>
- operand error: 0 - OK
- 14 - one of the operands is out of range.
- result error: 0 - OK
- 2 - the result is out of range.
- Example: SAY NUM2HEX('b11111111') -> FF 0 0
- SAY NUM2DEC('hFFFFFFFFF') -> FFFFFFFF 14 0
-
- NUMADD Adds two numbers
- NUMSUB Substracts one number
- NUMPROD Multiplies two numbers
- NUMDIV Integer division
- NUMMOD Modulo operation
- NUMOR Bit OR of two numbers
- NUMAND Bit AND of two numbers
- NUMXOR Bit XOR of two numbers
- NUMSHL 32 bit shift left
- NUMSHR 32 bit shift right
-
- Syntax: RC = NUMAND(num1,num2)
- num1 and num2 must be in decimal notation!
- The build in OR, AND and XOR function of REXX work on string
- basis and do not give a correct result for numbers!
-
- Returns: <result string> <operand error> <result error>
- operand error: 0 - OK
- 14 - one of the operands is out of range.
- result error: 0 - OK
- 2 - the result is out of range.
-
- Example: SAY NUMADD(255,255) -> 510 0 0 : OK
- SAY NUMPROD(4294967295,2) -> 4294967294 0 2 : invalid result!
- SAY NUMDIV(9999999999,2) -> 2147483647 14 0 : operand too large!
- SAY NUMSHL(2,4) -> 32 0 0 : 2 shifted left 4 times
- SAY NUMDIV(100,0) -> 2 0 2 : invalid result!

- RXNUM.DLL is shareware without any restrictions. I do not like to test
- any crippled shareware and I think you don't like it neither. Please
- register online on CompuServe or send your money by mail when turning from
- test phase to using phase.
