Float

A (single-precision 32-bit) floating point number has a decimal point. This data type is often simply called Float. This type uses less memory than the Double-precision floating-point number.

Comments

VBScript

The VBScript single floating-point type contains a single-precision, floating-point number in the range -3.402823E38 to 3.402823E38 for positive values.

JScript

JScript uses a generic "number" data type which corresponds to integer values as well as floating point values. There is no specific single-precision floating-point type in JScript.

PerlScript

PerlScript does not have a specific type that represents floating-point values.

Python

Python uses float to represent both single and double floating-point values.

C++

The C++ API uses float (4-byte single floating point number).

C#

The C# float type (System.Single) uses 7-digit precision and is in the approximate range ±1.5 × 10-45 to ±3.4 × 1038.
