Function modifiers

cast

Commentary

added in 0.4.16

Casts a value to a target type. Supports casts to string, integer, double, and boolean.

Casts are strictly to/from string, meaning you can't perform lossy casts like double to/from integer. Use the decimals function modifier you need to manipulate the underlying values.


Examples

Cast to string

Use string to cast any value to a string.

{
"_gen": "normalDistribution",
"mean": 50,
"sd": 2,
"cast": "string"
}
[
"49.345228976967846",
"45.60824138413649",
"53.303119625760935",
"48.49023437596098",
"47.491434292423676"
]

Cast to integer

Use integer to parse a string to an integer.

{
"_gen": "digitString",
"n": 5,
"cast": "integer"
}
[
98952,
73634,
58434,
16853,
17279
]

Cast to double

Use double to parse a string to a double.

{
"_gen": "constant",
"x": "10.25",
"cast": "double"
}
[
10.25
]

Cast to boolean

Use boolean to parse a string to a boolean. Invalid values become false.

{
"t": {
"_gen": "constant",
"x": "true",
"cast": "boolean"
},
"f": {
"_gen": "constant",
"x": "false",
"cast": "boolean"
},
"i": {
"_gen": "constant",
"x": "invalid",
"cast": "boolean"
}
}
[
{
"t": true,
"f": false,
"i": false
}
]
