They are both 4 bytes. Float to integer is always possibile without problems. Integer to float is not always good because float has the integer range reduced

"float has the integer range reduced" is not true

#

float can represent values that are out of range for int

In the mantissa part?

#

They are both 4 bytes, the semantic value wont be preserved

#

You can convert it directly but you wont get the same number

#

Because bytes are not used in the same wat
