get a number from string

J-M-L:
Well this is still not good

Serial.println(atoi(MyStr[strchr(MyStr,'e') + 1]);

As strchr() returns a pointer in the string, not the index of the ‘e’ in the array

It’s not cool to modify past posting without documentation then the conversation does not make any sense

Lol I'm blending 2 programming languages.
Ok

atoi(strchr(MyStr,'e') + 1)
