## conv()WE can convert any number from one mathematical base number system to another base number system by usingconv() function in MySQL. Here is the syntax
Here n is any number and base_from is base of n ( the number ) at present. base_to is the base of the number we want to covert. Minimum base value is 2 and maximum base value is 36. Let us try one example
Here number is b of base 16 , after conversion it will have base of 2 . The output is here
Now let us try one octal number
## Octal number to decimal ( base 10 )
In above code number 11 is of base 8 and after conversion it became decimal number of base 10. Here is our output
In conventional way it is 11=1x8^{1} + 1x8^{0} , so 11 in octal is equal to 9 in decimal. You can also use MySQL oct function to covert decimal number to Octal system
## Hex to binaryHex numbers have base of 16 and binary is of base 2
Output is
## Decimal to HexDecimal is of base 10 and Hex is of base 16
The output is here
## Convert numbers from decimal to Octal base systemWe can convert decimal number to octal number by using oct function. Here are examples
- SQL Math References
- LOG10() to get Log value with base 10
