Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a normalized double-precision number with a sign bit of 0, exponent bits of 10000000001, and mantissa bits of 1111111111111111111111111111111111111111111111111111, calculate the true value.

💡 Hint: Break it down: convert the exponent back to its true form and remember to include the leading 1 in the mantissa.

Challenge 2 Hard

Explain how computations using double-precision can lead to rounding errors during long calculations.

💡 Hint: Consider how floating-point arithmetic differs from integer arithmetic regarding precision.
