Numbers In 'Go'(Learn 'Go' - Part 7)

in #programming7 years ago

In Go, there are several types to represent numbers.

For Integers, we have

  • int8
  • int16
  • int32
  • int64
  • uint8
  • uint16
  • uint32
  • uint64

 
 

'uint' means unsigned integers and 8,16,32,64 represent how many bits each one use. 'int' represents signed integers and they can only be used for positive integers like 1,2,3 and so on.

We can also use 'byte' for 'uint8' and 'rune' for 'int32'.

 
 

For Floating numbers, we have

 

  • float32
  • float64

Using a larger integer type or floating number type increases its precision.

 
 

Besides the regular ones listed above, we also have some other types to represent numbers that come in use occasionally.

  • NaN ~ Not a Number

 

For complex numbers, we have

  • complex64
  • complex128

 

While dealing with numbers, we will need to use operators.

  • '+' for addition
  • '-' for subtraction
  • '*' for multiplication
  • '/' for division
  • '%' for modulus or remainder
