Float to integer |

I have got a float variable of 32 bits,
I am trying to make a casting to integer:
integer_variable = (int) float_variable;
The float variable contains some data, but after the above command, the integer_variable remains zero.
How can I solve this?
Thank you |

Help us out here and tell us what the data is!! If it is between 1 and -1 (negative exponent), the result of the conversion should be 0. Also, what is the expected range of data that you will be trying to convert? |

A really inefficient way to convert floats is to use sprintf to convert floats to an ascii string, you can then see what value you have and it may be a more convenient way to store things anyway. You can always use atoi() or atol() to convert the asciii to an int or long.
In your particular case, setup a number of test cases, it may be that casts are not doing what you want.
