As an example the decimal numbers 12345 are stored in a char array [5]. array [0] being 1 and array [4] being 5.

Also, pfloat1 and pfloat2 might not be correctly aligned for a float. The result here is: pfloat1 = 0.000000, pfloat2 = -6999176012340658176.000000 durham equality
Array : How can mixed data types (int, float, char, etc) be stored …
WebFloat.byteValue just truncates float value to 1 byte. public byte byteValue() { return (byte)value; } Besides, it's not clear what bytes you want. Is it IEEE 754 floating-point single-float bit layout? Then you can first convert it to int. int i = Float.floatToIntBits(1.1f); // see Float API, there are actually 2 options WebYou can make the array elements a discriminated union, aka tagged union. struct { enum { is_int, is_float, is_char } type; union { int ival; float fval; char cval; } val; } my_array[10]; The type member is used to hold the choice of which member of the union is should be used WebEx: Consider, Float variable f has 870.123400 i want to store it in a char array like a [0] = 8 a [1] = 7 a [2] = 0 a [3] = . a [4] = 1 a [5] = 2 a [6] = 3 a [7] = 4 a [8] = 0 a [9] = 0 thanks in advance. 04-22-2015 #4 laserlight C++ Witch Join Date Oct 2003 Location Singapore Posts 28,416 Originally Posted by vinoth14 crypto companies that went bankrupt
