float
float(x)
Convert a number, array, or string to a AbstractFloat data type. For numeric data, the smallest suitable AbstractFloat type is used. Converts strings to Float64.
Examples
julia> float(5)
5.0
julia> float(3.14)
3.14
julia> float([1, 2, 3])
3-element Array{Float64,1}:
1.0
2.0
3.0
julia> float("3.14")
3.14- The
floatfunction can be used to convert an integer or a floating-point number to aFloat64type. - It can also convert an array of numbers to an array of
Float64type, preserving the original values. - Strings representing numbers can be converted to
Float64type as well.
Common mistake example:
julia> float("hello")
ERROR: ArgumentError: invalid number format: "hello"In this example, the input string "hello" cannot be converted to a floating-point number. Make sure to provide valid numeric values or arrays of numbers when using the float function.
