Conversions between Fvec and Ivec
- Convert the lower double-precision floating-point value ofAto a 32-bit integer with truncation:int F64vec2ToInt(F64vec42 A); r := (int)A0;
- Convert the four floating-point values ofAto two the two least significant double-precision floating-point values:F64vec2 F32vec4ToF64vec2(F32vec4 A); r0 := (double)A0; r1 := (double)A1;
- Convert the two double-precision floating-point values ofAto two single-precision floating-point values:F32vec4 F64vec2ToF32vec4(F64vec2 A); r0 := (float)A0; r1 := (float)A1;
- Convert the signedintinBto a double-precision floating-point value and pass the upper double-precision value fromAthrough to the result:F64vec2 InttoF64vec2(F64vec2 A, int B); r0 := (double)B; r1 := A1;
- Convert the lower floating-point value ofAto a 32-bit integer with truncation:int F32vec4ToInt(F32vec4 A); r := (int)A0;
- Convert the two lower floating-point values ofAto two 32-bit integer with truncation, returning the integers in packed form:Is32vec2 F32vec4ToIs32vec2 (F32vec4 A); r0 := (int)A0; r1 := (int)A1;
- Convert the 32-bit integer valueBto a floating-point value; the upper three floating-point values are passed through fromA:F32vec4 IntToF32vec4(F32vec4 A, int B); r0 := (float)B; r1 := A1; r2 := A2; r3 := A3;
- Convert the two 32-bit integer values in packed form inBto two floating-point values; the upper two floating-point values are passed through fromA:F32vec4 Is32vec2ToF32vec4(F32vec4 A, Is32vec2 B); r0 := (float)B0; r1 := (float)B1; r2 := A2; r3 := A3;
