[Bug c++/20764] New: value won't fit in type

- Reply-to: gcc-bugzilla at gcc dot gnu dot org
Given the following C++ source code
float fred = 1.0e50;
The float data type maximum value is around 1.0e38 on my machine, so fred
will not fit.
gcc 3.4 snapshot for 20050401 fails to detect this.
dcb@linux:~/C++/Alphasrc> ~/gnu/20050401/results/bin/g++ -g -c -O2 -Wall floatVal.cc
dcb@linux:~/C++/Alphasrc> ~/gnu/20050401/results/bin/g++ -g -c -O2 -Wall -ansi
-pedantic floatVal.cc
Here is Intel icc 8.1 doing what I want
dcb@linux:~/C++/Alphasrc> icc -c floatVal.cc
floatVal.cc(2): warning #264: floating-point value does not fit in required
floating-point type
float fred = 1.0e50;
