Working with Integer data in TOML

TOML has good support to represent integer numbers.

 

integersDemo1.toml

a = 10
b = +10
c = -10
d = 0

 + sign for positive numbers is optional, and negative numbers are prefixed with – sign.

 

Use _ to enhance readability

You can use underscore (_) to enhance readability of large numbers.

 

largeNumbers.toml

creditCardNumber = 1234_5678_9012_3456
socialSecurityNumber = 999_99_9999

 

Positive integers can be expressed in binary, octal and hexa notation

 

numberConversion.toml

binary1 = 0b1111111
oct1 = 0o177
hex1 = 0x7F

 

Points to note

a.   By any chance if an integer is can’t be represented losslessly, an error is thrown.

b.   -0 and 0 are treated as 0.
