Nathalie Revol facts for kids

Nathalie Revol, born in 1967, is a French computer scientist. A computer scientist is like a super smart detective who solves problems using computers! Nathalie is known for her work on how computers do math, especially with numbers that have decimal points (like 3.14) and numbers that are part of a range (like "between 5 and 10").

She works as a researcher for the French Institute for Research in Computer Science and Automation (INRIA). This is a big research center in France. She is part of a special team that studies how computers handle numbers and calculations at the École normale supérieure de Lyon.

Nathalie's Journey in Computer Science

Nathalie Revol started her studies in computer science in 1987. She went to a school called ENSIMAG in Grenoble, France. In 1990, she earned a special engineering degree there.

At the same time, she also studied advanced math at Joseph Fourier University. She got another degree in applied mathematics in 1990.

Becoming a Doctor of Computer Science

Nathalie continued her studies and earned her PhD in 1994. Her special research was about how fast computers can do math calculations. She looked at how complex these calculations are when done at the same time.

After her studies, she worked as a temporary researcher. Then, in 1996, she became a professor at Lille University of Science and Technology.

Working at INRIA

In 2002, Nathalie joined INRIA as a full-time researcher. This is where she works today, helping to make computers better at math. Since 2020, she has been a top-level researcher there.

What Nathalie Revol Has Achieved

Nathalie Revol has made important contributions to how computers handle numbers. She helped create rules for how computers should do math with "interval arithmetic." This is a way for computers to work with ranges of numbers instead of just single numbers.

Setting Standards for Computer Math

She led a group that created the IEEE 1788 standard. This standard is like a rulebook for how computers should perform interval arithmetic. It helps make sure that different computers do these calculations in the same, correct way.

Creating Special Math Tools

With another scientist named Fabrice Rouillier, Nathalie helped create something called the MPFI library. This is a special set of computer tools. It allows computers to do math with very, very precise numbers and ranges. This is called "arbitrary-precision interval arithmetic."

Writing a Book About Computer Math

Nathalie Revol also helped write a book called Handbook of Floating-Point Arithmetic. This book is a guide to how computers handle numbers with decimal points. It's a very important book for people who study computer math. The first edition came out in 2010, and a second, updated edition was released in 2018.
