In Julia, float numbers can be created using decimal notation with a dot (.) or scientific notation with the e operator. The default floating point type in Julia is 64-bit double precision (Type: Float64).
Here are some examples:
1. Decimal notation:
x = 1.23
y = 4.56
2. Scientific notation:
a = 1e-6 # 1x10^-6
b = 3e5 # 3x10^5
3. Mathematical operations:
x = 5.0 + 2.5 # 7.5
y = 3.0 / 2.0 # 1.5
z = 2.0 ^ 3.0 # 8.0
4. Type conversion:
a = 4
b = Float64(a) # 4.0
c = convert(Float64, a) # 4.0
Note that Julia supports multiple types of floating point numbers:
- Float16: Half-precision floating-point number
- Float32: Single-precision floating-point number
- Float64: Double-precision floating-point number.
