float

float([X])

Converts the type of input data to FLOAT.

X (optional): Any data type, and can be in any data form.

Data of the FLOAT type, and the data form is the same as X。

Create a FLOAT variable with a default value of null.

x=float()
x // Output: null
typestr x // Output: 'FLOAT'

Convert a string that indicates a number.

x=float("123")
x // Outout: 123
typestr x // Output: 'FLOAT'

Convert a boolean value.

x=float([true, false])
x // Output: [1, 0]
typestr x // Output: 'FAST FLOAT VECTOR'

Convert data of the DOUBLE type.

x=123456789.1234567 // 16 digits
typestr x // Output: 'DOUBLE'

y=float(x)
y // Output: 123,456,792 (FLOAT accepts 9 digits at most)
typestr y // Output: 'FLOAT'

Create variables with positive and negative infinity values.

// Create a variable with a positive infinity value
posInf = float("inf")
posInf  // Output: ∞
typestr posInf // Output: 'FLOAT'
posInf > 1000000000 // Output: true

// Create a variable with a negative infinity value
negInf = float("-inf")
negInf  // Output: -∞
typestr negInf // Output: 'FLOAT'
negInf < NULL // Output: true
