Floating point numbers
Any decimal number can be written in the form of a number multiplied by a power of 10. For example: 1234=0.1234 ×104 and 12.34567=0.1234567 ×102. In 1234=0.1234 ×104, the number 0.1234 is mantissa or coefficient, and the number 4 is the exponent.
This technique is used to represent binary numbers.
This A Level Computer Science module introduces floating point numbers to your students, explaining:
- Representing numbers with decimal points in binary
- Floating-point binary representation
- Improving precision when representing floating-point numbers
- Arithmetic operations
