Bicep provides the bool function for converting values to a boolean.

Most of the logical functions in Azure Resource Manager templates are replaced with logical operators in Bicep.

bool

bool(arg1)

Converts the parameter to a boolean.

Namespace: sys.

Parameters

Parameter	Required	Type	Description
arg1	Yes	string or int	The value to convert to a boolean. String value "true" with any combination of upper and lower case characters (for example "True", "TRUE", "tRue", "true") are considered to be equivalent and represent the boolean value of `true`, otherwise `false`. Integer value 0 is considered to be `false` and all other integers are considered to be `true`.

Return value

A boolean of the converted value.

Examples

The following example shows how to use bool with a string or integer.

output trueString1 bool = bool('true')
output trueString2 bool = bool('trUe')
output falseString1 bool = bool('false')
output falseString2 bool = bool('falSe')
output trueInt2 bool = bool(2)
output trueInt1 bool = bool(1)
output trueIntNeg1 bool = bool(-1)
output falseInt0 bool = bool(0)

The output from the preceding example with the default values is:

Name	Type	Value
trueString1	Bool	true
trueString2	Bool	true
falseString1	Bool	false
falseString2	Bool	false
trueInt2	Bool	true
trueInt1	Bool	true
trueIntNeg1	Bool	true
falseInt	Bool	false
