| Alright. Here is an attempt to get a definitive answer. I know that integers need to be within the range -2147483648 to +2147483647. But what about the floats.. what is the range in blitz. I know that there is a standard upper and lower bounds, but the documentation in blitz does not state this. Any takers? |

| The largest float could be represented as a 128-bit integer consisting of 24 ones followed by 104 zeroes. N = (2^24) - 1 in base two is 24 ones. So the largest float is N * (2^104), i.e. N with another 104 zeroes on the end. In base ten that's about 3.402823466e38. The 'most negative float' is the same number times -1. Here's the relevant #define from FLOAT.H for Visual C++ #define FLT_MAX 3.402823466e+38F |

| in another thread mark said that blitz only stores 6 decimals.. can't find the thread now, but a similar one is at http://www.blitzbasic.com/bbs/posts.php?topic=9385 |
