Booleans

a boolean represents a truth value.

in Ayla, a boolean can be either:

  • yes (true)
  • no (false)

boolean expressions​

booleans are often produced by comparisons:

egg x = 5

putln(x > 3)   // yes
putln(x == 10) // no

output:

yes
no

comparison operators include:

  • == (equal)
  • != (not equal)
  • > (greater than)
  • < (less than)
  • >= (greater than or equal)
  • <= (less than or equal)

logical operators​

You can combine boolean values:

egg a = yes
egg b = no

putln(a && b)  // no
putln(a || b)  // yes
putln(!a)      // no

output:

no
yes
no

where && is AND, || is OR, and ! is NOT
