Convert Float to Integer
Convert a floating-point number to an integer by truncating the fractional part.

Problem statement
Given a single floating-point number, return its integer conversion using Python's default behavior: drop the fractional part (truncate toward zero). Do not round — simply convert to int.
For example, 3.9 becomes 3, -2.7 becomes -2, and 0.0 becomes 0.
Task
Write a function that converts a float to an integer using Python's truncation behavior (toward zero).
Examples
Input format
A single floating-point number is passed as the only argument to the function convert_float_to_int.
Output format
Return an integer that is the result of converting the input float to int.
Constraints
- Use Python's int conversion semantics (truncate toward zero).
- Input will be a finite float (no need to handle NaN or infinity for this exercise).
Samples
Sample 1
Input
convert_float_to_int(-2.7)
Output
-2
Negative floats truncate toward zero, so -2.7 -> -2.
