Booleans

Overview

Booleans in KSL are represented with bool. There are no special rules for interacting with booleans. They will be stored as a full byte in storage unless manually tweaked. The only considerations to take into account are how numbers are casted into booleans as they may differ from other programming languages.

Casting Support

Types that can be cast to bools:

• Integer (via <value>'bool)
• Float (via <value>'bool)

Types that bools can be cast to:

• Integer (via <value>'int)
• Float (via <value>'float)

Method Support

There are no methods supported for booleans.

Examples

bool x = true;

Notes

A quick note on casting to booleans:

In some languages casting integers or floats to a boolean may be different. In KSL all integers other than 0 are cast to true. Similarly, all floats other than 0.0 are cast to true:

bool'1;         // true
bool'0;         // false
bool'252466642; // true
bool'-35;       // true

bool'0.0;       // false
bool'135.03111; // true
bool'-135.77;   // true
