Detailed Description

Converting between different numerical bases.

In a positional number system, the value of each digit is determined by which place it appears in the full number. The lowest place value is the rightmost position, and each successive position to the left has a higher place value.

For example, the value of the binary number 10011 is determined by computing the place value of each of the digits of the number:

            1          0          0          1          1       the binary number
            2⁴         2³         2²         2¹         2⁰      place values
         (1 * 2⁴) + (0 * 2³) + (0 * 2²) + (1 * 2¹) + (1 * 2⁰)
       =    16    +    0     +    0     +    2     +    1
       =    19

Function Documentation

Binary2Denary()

def _01d_dec2bin.Binary2Denary

(

bStr

)

Converts a binary string to a denary integer.

Parameters

bStr	a binary string.

Returns

int(bStr,2).

Referenced by main().

dec2hex()

def _01d_dec2bin.dec2hex

(

n

)

Converts a denary integer to hexadecimal.

Parameters

n	an integer.

Returns

hex(n).

Referenced by main().

Denary2Binary()

def _01d_dec2bin.Denary2Binary

(

num

)

Converts denary integer to a binary string.

Parameters

num	an integer.

Returns

binary string.

Referenced by main().

hex2dec()

def _01d_dec2bin.hex2dec

(

s

)

Converts a string or number to a plain integer.

The radix parameter gives the base for the conversion (which is 10 by default) and may be any integer in the range [2, 36], or zero. If radix is zero, the proper radix is determined based on the contents of string; the interpretation is the same as for integer literals.

Parameters

s

Returns

int(s, 16).

Referenced by main().

int2bin()

def _01d_dec2bin.int2bin	(		n,
			count = 24
	)

Converts an integer to a binary string representation with an specified number of bits.

Parameters

n	an integer.
count	number of digits.

Returns

the binary of integer n, using count number of bits.

Referenced by main().

main()

def _01d_dec2bin.main
