+# BinTools
+
+A [raycast](https://raycast.com/) calculator plugin for binary, decimal, hex and octal numbers.
+
+## Usage
+
+Enter your calculation in the text field, by using the following prefixes for the different number systems:
+
+- `0b` for binary
+- `0x` for hexadecimal
+- `0o` for octal
+
+The result will be calculated on the fly and displayed live under your calculation.
+If you want to calculate floating point numbers, you can use the `.` or `,` as decimal separator.
+Currently only decimal and binary fixed point numbers are supported as input.
+
+### Examples
+
+- `0b101 + 0x1` will result in `0b110` or `6` in decimal
+- `0b0101+0o5-0xf`  will result in `-0b101?` or `-5` in decimal
+- `0b0.1` will result in `0.5` in decimal
