Single Vs Int32

What is the equivalent data type for single-precision 32-bit IEEE 754 floating point in Xojo? Is it Int32 or Single?

Well it certainly isn’t Int32 (or any other datatype that contains the letters “INT”)… those are INTEGER datatypes

Single precision, usually used to represent the “float” type in the C language family (though this is not guaranteed). This is a binary format that occupies 32 bits (4 bytes) and its significand has a precision of 24 bits (about 7 decimal digits).

Double precision, usually used to represent the “double” type in the C language family (though this is not guaranteed). This is a binary format that occupies 64 bits (8 bytes) and its significand has a precision of 53 bits (about 16 decimal digits).

and to target both 32-bit and 64-bit … you can use CGFloat (read the LR)
