Float32
Float32(x [, mode::RoundingMode])
Create a Float32 from x. If x is not exactly representable then
mode determines how x is rounded.
julia> Float32(1/3, RoundDown)
0.3333333f0
julia> Float32(1/3, RoundUp)
0.33333334f0See get_rounding for available rounding modes.
Examples
Float32(x [, mode::RoundingMode])
Create a Float32 from x. If x is not exactly representable, then mode determines how x is rounded.
julia> Float32(1/3, RoundDown)
0.3333333f0
julia> Float32(1/3, RoundUp)
0.33333334f0In the above examples, Float32 is used to create a single-precision floating-point number from a given value (x). The mode parameter is optional and specifies the rounding mode to be used if x cannot be represented exactly as a Float32. The available rounding modes can be obtained using the get_rounding function.
Note: The suffix f0 in the output represents a Float32 value.
It's worth mentioning that the Float32 function can be used with various types of input, including integers, floating-point numbers, and expressions involving mathematical operations.
Example:
julia> Float32(10)
10.0f0
julia> Float32(3.14)
3.1400001f0
julia> Float32(sqrt(2))
1.4142135f0In the first example, Float32 converts the integer 10 into a single-precision floating-point number. The second example demonstrates the conversion of the floating-point number 3.14. The third example shows the conversion of the square root of 2 using the sqrt function.
Please note that Float32 may introduce round-off errors when representing numbers that cannot be expressed exactly in binary floating-point format.
